Authors: Riyad Md. Nur Hossain , Sunny Adil , Khatun Marzia , Rahman Sabrina , Ahmed Sheikh Rashel Al
Published: April 2022

This study reports on performance enhancement in a solar cell
introducing Sb2S3 as hole transport layer (HTL)along WS2 as buffer
layer. We have investigated photovoltaic (PV) characteristics by
utilizing SCAPS-1D. A comparative observation on PV performances of
conventional CZTS/CdS with proposed CZTS/WS2 and Ni/Sb2S3/CZTS/WS2
/FTO/Al solar cells is presented. It is revealed that “spike like”
band structure at CZTS/WS2 interface having smaller conduction band
offset makes it potential alternative to commonly used CdS buffer. This
study also evaluates that Sb2S3 as an HTL proposed at back of CZTS
enhances performances by reducing carrier recombination at back
interface with appropriate band alignment. The impacts of thickness,
carrier concentration of different layers, and bulk defect density in
CZTS as well as defects at interfaces on performances are analyzed. The
influences of temperature, work function as well as cell resistances are
also explored. Optimum absorber thickness of 1.0 µm along doping of 10
17 cm-3 is selected. A maximum efficiency of 30.63% is achieved for the
optimized CZTS cell. Therefore, these results suggest that Sb2S3 as
HTLand WS2 as buffer layer can be employed effectively to develop highly
efficient and low-cost CZTS solar cells.

Published: April 2022

Pervaporation is considered to have great application potential in the
field of organic solvent dehydration. However, the development of
pervaporation is hampered by the separation performance of current
membranes. In this study, covalent organic framework pervaporation
membranes were fabricated through contra-diffusion self-assembly
strategy for organic solvent dehydration. The polyacrylonitrile (PAN)
substrates were pretreated by oxygen plasma to control the diffusion
rate and confine the reactive region. Superoxide radicals were generated
on the surface of the PAN substrate to assist the growth of TpPa.
Therefore, the time of contra-diffusion was shortened to obtain a TpPa
membrane, which exhibited a superior separation factor of 1491 and a
high permeation flux of 2530 g m-2 h-1 for 90 wt% isopropanol/water
mixture. The separation performance of the TpPa membrane could be stable
for over 100 h, exhibiting great potential in organic solvent
dehydration.

Impaired pancreatic β-cell function and insulin secretion are hallmarks of type 2 diabetes. miRNAs are short, noncoding RNAs that silence gene expression vital for the development and function of β cells. We have previously shown that β cell–specific deletion of the important energy sensor AMP-activated protein kinase (AMPK) results in increased miR-125b-5p levels. Nevertheless, the function of this miRNA in β cells is unclear. We hypothesized that miR-125b-5p expression is regulated by glucose and that this miRNA mediates some of the deleterious effects of hyperglycemia in β cells. Here, we show that islet miR-125b-5p expression is upregulated by glucose in an AMPK-dependent manner and that short-term miR-125b-5p overexpression impairs glucose-stimulated insulin secretion (GSIS) in the mouse insulinoma MIN6 cells and in human islets. An unbiased, high-throughput screen in MIN6 cells identified multiple miR-125b-5p targets, including the transporter of lysosomal hydrolases M6pr and the mitochondrial fission regulator Mtfp1. Inactivation of miR-125b-5p in the human β-cell line EndoCβ-H1 shortened mitochondria and enhanced GSIS, whereas mice overexpressing miR-125b-5p selectively in β cells (MIR125B-Tg) were hyperglycemic and glucose intolerant. MIR125B-Tg β cells contained enlarged lysosomal structures and had reduced insulin content and secretion. Collectively, we identify miR-125b as a glucose-controlled regulator of organelle dynamics that modulates insulin secretion.

Published: April 2022

Postprandial dyslipidemia is a metabolic condition commonly associated with insulin-resistant states, such as obesity and type 2 diabetes. It is characterized by the overproduction of intestinal chylomicron particles and excess atherogenic chylomicron remnants in circulation. We have previously shown that glucagon-like peptide 2 (GLP-2) augments dietary fat uptake and chylomicron production in insulin-resistant states; however, the underlying mechanisms remain unclear. Previous studies have implicated nitric oxide (NO) in the absorptive actions of GLP-2. In this study, we report a novel role for neuronal NO synthase (nNOS)–mediated NO generation in lipid uptake and chylomicron formation based on studies in C57BL/6J mice, nNOS−/− mice, and Syrian golden hamsters after intraduodenal and oral fat administration. GLP-2 treatment in wild-type (WT) mice significantly increased postprandial lipid accumulation and circulating apolipoprotein B48 protein levels, while these effects were abolished in nNOS−/− mice. nNOS inhibition in Syrian golden hamsters and protein kinase G (PKG) inhibition in WT mice also abrogated the effect of GLP-2 on postprandial lipid accumulation. These studies demonstrate a novel mechanism in which nNOS-generated NO is crucial for GLP-2–mediated lipid absorption and chylomicron production in both mouse and hamster models. Overall, our data implicate an nNOS-PKG–mediated pathway in GLP-2–mediated stimulation of dietary fat absorption and intestinal chylomicron production.

Published: April 2022

Objective:
The
prevalence of hypertension is higher in children and adolescents with type 1 diabetes
(T1D) compared to those without. This retrospective analysis of a large cohort
of children and adolescents with T1D from the SWEET international consortium of
pediatric diabetes centers aimed to (i) estimate the prevalence of elevated
office blood pressure (BP) and hypertension and (ii) investigate the influence
of BP measurement methodology on the prevalence of hypertension.

Research design and methods: A total of 27,120 individuals with T1D,
aged 5-18 years were analyzed. Participants were grouped into those with BP
measurements at ≥3 visits (n=10,440) and <3 visits, (n=16,680) per year, and
stratified by age and sex. A subgroup analysis was performed on 15,742 individuals
from centers providing a score indicating BP measurement accuracy.

Results:
Among
participants with BP measurement at ≥3 visits, the prevalence of hypertension
was lower compared with those with <3 visits (10.8% vs 17.5% p<0.001),
whereas elevated BP and normotension was higher (17.5% and 71.7% vs 15.3% and 67.1%
respectively; both p<0.001). The prevalence of hypertension and elevated BP
was higher in individuals aged ≥13 years than in younger ones (p<0.001) and
in males than females (p<0.001). In linear regression models, systolic and
diastolic BP were independently determined by the BP measurement methodology.

Conclusions:
The
estimated prevalence of elevated BP and hypertension in children and
adolescents with T1D is almost 30% and depends on the BP measurement methodology.
Less frequent BP evaluation may overestimate the prevalence of hypertension.

Fluids are a shape of a matter which have substance liquids, gases and plasmas. In our daily life, fluids become important part, such as part of our blood and also help our body getting nutrients. It is well known that fluid motion can be described in mathematical model in especially in form of partial differential equations (PDE) and called as Navier Stokes EquationsÂ  (NSE). The Navier Stokes equation is derived from balance of conservation of mass and conservation of momentum. In this paper, we consider the solution formula of the linearized of the Navier Stokes Equation (NSE) with the initial boundary value (IBV) problem in half space without surface tension. The model problem under consideration covers of non-linear fluid type. We solve the solution formula of velocity and density of the model problem by using Fourier transform and partial Fourier transform method. The strategy geting the solution of the model problem is based on the analysis of some resolvent of the model problem which obtained by using Laplace transform of the Stokes equations. Therefore, In particular, the formula of velocity and density of the Stokes equation are obtained.

A Streaming Media Recompression Transmission Scheme for Agricultural Machinery Monitoring
Authors: Lin Shengken , Wu Honggang , Zhang Tianshun , Fei Jiajie , Lu Shaokun
Published: April 2022

Place a camera on the agricultural machinery, the video collected by the camera is transmitted by means of a wireless network to enable the operator to monitor the operation of the machinery and provide decisions accordingly when necessary. As video data contains large capacity, and the farmlands are distributed widely and remotely, it is difficult to ensure the stability of the transmission network. In this research, a binary recompression method was proposed to perform a secondary compression on the video sequence compressed by the encoder, which solved the problem of video transmission in dynamic network by reducing the number of bytes of data on the communication channel. The core idea is to change the distribution of the original sequence of "0" and "1" symbols in binary by designing mapping rules and compression rules through the idea of binary rearrangement, so that the same symbols can be gathered together as much as possible, thereby increasing the probability of compression. In the end, a test system was set up to verify that the recompressed transmission scheme proposed in this paper was able to effectively improve the quality of video transmission in farmlands.

The oil and gas fields of Forecarpathian oil and gas region are compared with the structure of earth’s crust and regional faults. Most of the oil and gas condensate fields are localized in Borislav-Pokutia nappe over Precarpathian Fault zone. The majority of gas fields are located in under thrusting zone of the Sambir fault, which is a gently dipping detachment connected with the Forecarpathian fault and other faults of autochthonous basement. The regional gravity low of Carpathian Foredeep is also limited from northeast by the Sambir fault and from the southwest by the Uzhok fault. The Forecarpathian fault tends to the central part of gravity low. Transverse Tyachev-Nadvorna fault displaces the gravity low and delimits the oil and gas condensate fields. Velocity model along the wide-angle reflection and refraction PANCAKE profile shows a deep (25 km) sedimentary trough under the Carpathian Orogen. The Forecarpathian fault coincides with a jump of the Moho under the trough. Along the RomUkrSeis profile under Carpathian Orogen there were revealed a sedimentary trough as deep as 15 km and a low-velocity domain under the trough. From northeast, the trough is limited by the Forecarpathian fault, which goes up to the keel structure of the Moho discontinuity. Structure of the trough under Carpathian Orogen reflects development of East European Platform margin. The earliest stage of the formation of Baltica paleocontinent passive margin is seen in the structure of the trough’s lower part. Autochthonous basement under Borislav-Pokutsky and Skiba nappes includes a Riphean Massif limited by the Krakovets, Forecarpathian and Uzhok faults. The oil and gas condensate fields are located above the Riphean Massif.

The purpose of this article is to analyze the fault system and the structure of the earth’s crust in the Forecarpathian oil and gas region, as well as their relationship with the distribution of oil and gas deposits, taking into account new WARR profiles and other geological and geophysical data.

The article investigates that due to the development of scientific and technological progress human rights are becoming increasingly relevant. Today, a new dimension of human rights is emerging - the fourth generation of human rights, providing for the human right to gender reassignment, organ transplantation, same-sex marriage, euthanasia, and so on. The problem of euthanasia attracts special attention of scientists. For the theory of law, the problem of euthanasia and its relationship with the law are of particular interest. In legal science, scholars have studied various aspects of the legalization of euthanasia, including countries such as Austria, Azerbaijan, Belgium, Greece, Georgia, Denmark, India, Iceland, Spain, Italy, the Netherlands, Germany, Poland, Portugal, Switzerland and Japan, but it seems is little studied is euthanasia in the legal systems of the United States and Canada. Today in the United States, the legal regulation of euthanasia is determined by the federal territorial structure of the state, where states can establish their own laws, this also applies to euthanasia. Euthanasia is allowed in 9 states, including Washington, Vermont, Hawaii, California, Colorado, Maine, Montana, New Jersey, Oregon and the District of Columbia. In Canada, a prerequisite for acceptance. The Law "On Amendments to the Criminal Code and Amendments to Other Laws (Regarding Medical Care at Death)" became the case of Carter v. Canada. The Law “On Amendments to the Criminal Code and Appropriate Amendments to Other Laws (Concerning Medical Care at Death)” at the federal level establishes the basis for the provision of medical care at death throughout the country. As for the provinces and territories of Canada, they have the power to legislate on death care, provided that they do not conflict with federal law. Most provinces and territories have adopted guidelines and policies for death care. Quebec is the only province that has passed a law, which regulates medical care at death.
Arrange as an object of copyright: concept, essence, protection
Authors: Buravska А.А.
Published: April 2022

The article is dedicated to the study of the problems of legal regulation of arrangements as an object of copyright. The urgency of the issue is due to the increasing demand for the creation of this object of copyright and the imperfection of its legal regulation. The methodological basis of the study consists of a number of general scientific and special scientific methods, in particular, comparison, generalization, dialectical and formal-legal method, as well as systematic and complex analysis. In the article, the opinions of scholars and legislative provisions on arrangements, derivative works and musical works are analysed and based on the analysis the concept of the term "arrangement" is given, and its essential features are defined. Thus, an arrangement is objectively expressed, a creative reworking of another existing work, expressed through sounds and consists of arranging another piece of music (for other instruments or folds), and/or processing its melody for performance on a musical instrument or voice with accompaniment. The essential features of an arrangement are considered to be the following: a creative reworking of another existing work; internal completeness and motivation of the whole; individualisation of the work; an objective form of expression; the need to express the essence through different sounds; and dependence on the original musical work. The article focuses on jurisprudence in the field of disputes related to the infringement of the rights of the author of the original work when performing an arrangement and creating a derivative work. The provisions concerning the means of copyright protection for arrangements are summarised. The state of the law in the field of legal regulation of arrangements and copyright and derivative works, in general, is analysed. Article 1 of the Law of Ukraine "On Copyright and Related Rights" is proposed to be supplemented by the term "arrangement" to be understood in accordance with the above.

The work is devoted to the payment of child support, determining the mechanism of child support, if one of the parents is abroad;According to Article 8 of the Law "On Child Protection" in Ukraine, every child has the right to a standard of living sufficient to satisfy his or her physical, intellectual, moral, cultural and spiritual, and social development. 51 part 2 of the Constitution of Ukraine and Article 180 of the Family Code of Ukraine (hereinafter - the IC of Ukraine), Parents are obliged to raise children to adulthood. The child must be in a family whose parents voluntarily fulfill their responsibilities for its upbringing.However, the right to custody of children and parental responsibilities are sacred and inviolable. Ensuring a proper standard of living, nutrition and education for children is not always correctly implemented in our country. The obligation of parents to maintain their children arises from a court decision or agreement between parents . Few unscrupulous parents try to avoid the court's liability for alimony payments, resorting to these techniques,For example: avoiding formal employment or getting a minimum wage. Expenses, transfer of property that can be levied, concealment of the Contractor, travel abroad, etc. Non-universal Demographic agreement between parents on the payment of alimony, in recent years, in order to strengthen the protection of children's rights to proper custody, the IC of Ukraine has undergone fundamental changes in the supervision of alimony obligations.Therefore, it is necessary to conduct a scientific analysis of the new legislation. It provides for the obligation of parents to maintain their children. These issues are mainly related to the minimum guaranteed amount of alimony and the recommended minimum amount of alimony, the circumstances listed. The court takes these factors into account when determining the amount of alimony and the amount of income. Alimony payer, which is collected in favor of the child, alimony is indexed.New version of the Law on Enforcement Proceedings of Ukraine Some changes have been made to the procedure for execution of decisions, and the range of measures that affect the executor's alimony payers has been expanded. Enforcement provides alimony through the use of procedural means and methods of coercion to persons who refuse voluntarily perform their alimony duties
Legal protection against unfair competition under the economic legislation of Ukraine
Authors: Tymchenko L. M. , Shtunder V.
Published: April 2022

The article examines the legal nature of unfair competition, regulations governing competition, methods of protection of economic entities in commodity markets, as well as the application of sanctions for violations of Ukrainian legislation on economic competition. According to the Law of Ukraine "On Protection against Unfair Competition", unfair competition is any action in competition that contradicts the rules, trade and other fair practices in business. Unfair competition includes the misuse of an entity’s business reputation, the creation of barriers to the entity’s competition and the achievement of undue competitive advantages, the unlawful collection, disclosure and use of trade secrets. The main methods of unfair competition include economic espionage, counterfeiting of competitors, bribery and blackmail, misleading consumers, fraud with business reporting, currency fraud, concealment of defects and more. The article considers the concept of fair and unfair competition from the point of view of different scientists. There are different approaches to the concept of "unfair competition" in the scientific doctrine, for example, the scientist N. Saniakhmetov notes that "unfair competition is a violation of rules of conduct that have developed, are widely used in business and are recognized by entrepreneurs as mandatory business rules that harm relations of fair competition and freedom of entrepreneurial activity ". According to O. Bezukh, "unfair competition arises as a result of illegal use of other people's intellectual products for commercial purposes, business reputation, other achievements of enterprises, goods or activities of a competitor, misleading consumers about competitors and gaining illegal advantages in competition." The general definition of unfair competition is contained in the Paris Convention for the Protection of Industrial Property, so according to this document, unfair competition is any act of competition that is contrary to fair practice in industrial and commercial matters. The article analyzes the mechanisms of combating unfair competition, highlights the administrative and judicial methods of combating unfair competition. It turned out that the body that deals with the fight against unfair competition is the Antimonopoly Committee. The article analyzes judicial practice in recent years. The provisions of foreign legislation on combating unfair competition have also been studied.

The article considers the issue of material support of the personnel of the State Service for Special Communications and Information Protection of Ukraine. It is noted that the social security of its personnel has a significant impact on the quality and efficiency of the State Service for Special Communications and Information Protection of Ukraine. One of the areas of social protection is called material, which is that, in addition to the actual financial support in the form of wages, they can receive additional material support, which includes a number of allowances, surcharges, bonuses and compensations that can claim civil servants provided that they meet certain criteria specified in the legislation. It is noted that the material direction of social protection of this category of workers is characterized by the following features: it is realized in the form of allowances, surcharges, bonuses and compensations; the size of such types of social protection is either directly provided by law or determined directly by the head of the civil service; the types of material direction of social protection of employees, in fact, are components of their wages and are introduced in order to provide additional social protection given the functions they perform and the risks they face.

It is concluded that the material support of the personnel of the State Service for Special Communications and Information Protection of Ukraine consists of allowances, surcharges, bonuses and compensations, the amounts of which are directly provided by law or determined directly by the head of the civil service and are part of their salaries social protection. The signing by the President of Ukraine of the Decree on the decision of the National Security and Defense Council of Ukraine of October 22, 2021 "On the Concept of reforming the State Service for Special Communications and Information Protection of Ukraine" is a step in the right direction. and information protection of Ukraine needs improvement.

Authors: Yaroshenko A. S. , Duma A. A. , Marochko A. A.
Published: April 2022

The article is devoted to the study of legal issues of forest use and protection in Ukraine, in terms of the organizational and legal mechanism for the protection of forest resources.Today, the issue of protecting forest resources by building a proper organizational and legal mechanism for their protection is becoming increasingly relevant. In nature, everything is interconnected and interdependent. All natural objects make up a single space of the Earth's territory, and it is necessary to understand that by preserving the Forest, Society also preserves other natural objects. Sustainable development of the forest industry will only be ensured by a system of Public Administration that simultaneously implements three goals – economic, environmental and social.The article deals with the issues of legal protection of forests as one of the main types of Natural Resources in Ukraine, as well as suggests ways to improve the legal regulation of forest relations. The main focus is on the analysis of scientific literature and legislative acts regulating the use and protection of forests. The relevance of improving the legal regulation of forest use is primarily related to such shortcomings of forest legislation as insufficient provision of forest protection from illegal logging, unsatisfactory Organization of forest protection, forest supervision and control, unclear division of powers between subjects of power in the field of forest management, imperfect measures to restrict the illegal export of forest materials.It is concluded that it is necessary to invest in forestry both by state bodies and large entrepreneurs, since today few people invest in forestry activities to preserve the forest areas of our state.

Published: April 2022

The article is devoted to judicial lawmaking and its features. In article is analyzed one of the most common question that is often asked by legal scholars and that still has no definitive answer, the question that has spurred sharp debates and discussions: "Do judges create rules of law?"

Naturally, it is the judiciary,  that is the court, called to administer justice. In resolving court cases, the court is obliged to use the rules of law created by the authorized bodies. However, there are situations when certain relationships remain unresolved. This is primarily due to the fact that relations in society are developing faster than the law itself. The court has no right to deny a citizen a decision only because the law lacks a relevant rule of law. Therefore, the judge in each case takes responsibility - creates a rule of law to decide the case. The process of judges creating rules of law is called lawmaking.

Considerable attention was paid to the historical origins of judicial lawmaking, the positions of the most prominent jurists on this topic were analyzed, among them, H. Hart, R. Dworkin, H. Kelzen. The views of retired judges of the Constitutional Court of Ukraine Mykola Ivanovych Kozyubra and Stanislav Volodymyrovych Shevchuk on this issue were also taken into account. It is emphasized that after the First World War the bodies of constitutional control in European states tend to change the provisions of the legislation by their decisions. This indicates the existence of judicial lawmaking.

We have concluded that judges do create rules of law. Moreover, law-making is an immanent feature of justice, that is, one that follows from its inner nature. Judges create rules of law regardless of the type of legal family, regardless of whether judicial precedent is recognized as a source of law or not.

Authors: Sharipov F. F. , Xu Man
Published: April 2022

Innovation is the first driver of development. The integration of the payment industry and mobile operations, the Internet, e–commerce, and other industries has created new opportunities for innovation and the development of payment services. Banking financial institutions, being the main part of the payment services market, assume the role of the main provider of non>cash payment services. The integration of non–cash payment instruments and bank management functions continues to deepen, and industry applications are becoming more mature. Through cooperation and exchange between China and Russia, as well as the development of the cultural economy, tourism, trade and other areas, Russia has adopted such Chinese non–cash payment methods as Alipay, WeChat and UnionPay. This has played an active role in improving the diversification of the transaction channels of two peoples, as well as in personalization and simplification of payment instruments, and it is very consistent with the requirements of convenience and efficiency of modern payments.

MAGNETIC PROPERTIES OF PrFe₁₁Ti ALLOYS BY Co AND Zr DOPING
Authors: BENEA D.
Published: April 2022

Theoretical investigations on the electronic and magnetic properties (magnetic moments, magneto-crystalline anisotropy, exchange-coupling parameters) of the PrFe11-xCoxTi (x = 0 – 3) and Pr0.8Zr0.2Fe11Ti alloys are presented. Our calculations show that Co for Fe doping in PrFe11-xCoxTi maximize the calculated total magnetic moment and magnetocrystalline anisotropy energy (MAE) for x = 1. The calculated exchange-coupling parameters for the first neighbours of each Fe site (8i, 8j and 8f) show an increase by increasing the Co content suggesting higher Curie temperatures for Co doped PrFe11Ti-based alloys. On the other hand, the Zr for Y substitution in Pr1-yZryFe11Ti (y = 0 - 0.2) decreases MAE without a noticeable decrease of the calculated total magnetic moment. Zr doping has opposite effects on the exchange coupling parameters Jij for different spin pairs. As consequence, any significant changes of the Curie temperatures are predicted for Zr doped PrFe11Ti based alloys in the investigated doping range.

Published: April 2022

Technetium radiopharmaceuticals remain the most widely available and cost-effective compounds used in nuclear medicine imaging. However, exact information regarding the chemical structure of these compounds is scarce. In this study we present a spectroscopic investigation of Hexakis (2-methoxy-2-methylpropylisonitrile) (MIBI) Technetium (99mTc) (99mTc-sestamibi). Surface Enhanced Raman Scattering spectra of the ligand and the Technetium sestamibi complex were recorded. For the later, the measurements were recorded in solution as administered to patients and at different moments from the time of preparation in order to monitor its stability. The information provided by the vibrational characterization of the MIBI ligand allowed us to understand spectroscopic features pertaining to the SERS spectra of the Technetium complex.
NEAR ROOM-TEMPERATURE TEMPERATURE MAGNETOCALORIC EFFECT IN Pr₀.₆₃₋ₓHoₓSr₀.₃₇MnO₃ MANGANITES
Authors: LUDOȘAN Alexandra , DEAC I.G.
Published: April 2022

Near room-temperature magnetic and magnetocaloric properties of the compounds Pr0.63-xHoxSr0.37MnO3 (x=0, 0.05) were investigated. The parent compound Pr0.63Sr0.37MnO3 has a large magnetocaloric effect around its Curie temperatures of about 300 K. Partially replacing of Pr3+ ions with Ho3+ ions in Pr0.63Sr0.37MnO3 gives rise to disorder which leads to the decrease of the Curie temperature without a significant reduction of the magnetocaloric effect. The samples were prepared by solid state reaction and were found to be single phase by x-ray diffraction. The magnetic measurements reveal paramagnetic to ferromagnetic second order phase transitions. For the sample with x = 0, the magnetic entropy change |ΔSM| was in the range from 1.91 J/kg٠K (RCP = 42 J/kg) for μ0 ΔH = 1 T to 4.86 J/kg٠K (RCP = 184 J/kg) for μ0 ΔH = 4 T. For the sample with x = 0.05, the magnetic entropy change |ΔSM| was in the range from 1.61 J/kg٠K (RCP = 57.9 J/kg) for μ0 ΔH = 1 T to 4.38 J/kg٠K (RCP = 236 J/kg) for μ0 ΔH = 4 T and Tc = 216 K. These values recommend these materials to be potential candidates to be used in near room-temperature refrigeration applications.

Published: April 2022

Understanding of underlying physics related to the Perpendicular Magnetic Anisotropy (PMA) in magnetic heterostructures represents a major issue for its exploit in random-access memory (MRAM) devices. Using ab-initio analysis, we reveal some basic aspects related to the anatomy of PMA and its variation with electric field in various X/Fe/MgO(001) multilayer configurations (X=Cr, Au, V, Ag, Pt, Pd,…) compatible with standard experimental architectures of magnetic tunnel junction devices. Our study quantifies and underlines the significant role of the Rashba interfacial field on PMA. We explain and correlate the sign, the magnitude, and the electric field dependence of the PMA, the Rashba coefficient αR and the Dzyaloshinskii–Moriya (DMI) asymmetric exchange interaction parameter. Moreover, when varying the Fe thickness in X/Fe/MgO(001) systems, we observe oscillations of PMA with the number of Fe monolayers, explained within the framework of quantum wells of the Δ1 Bloch symmetry electrons in Fe. Further atomistic micromagnetic simulations including different Fe layer thicknesses and the corresponding PMA predict macroscopic magnetization characteristics in realistic experimental systems.
