title: Temperature dependence of overdamped 2D fluctuations in metal halide perovskites

description: All inorganic perovskites has been attracting great attentions because of their promising optoelectronic properties, ultralow thermal conductivity for both photovoltaic and thermalelectric applications. Zone-boundary soft modes that associated with the octahedral rotations has been found to be highly anharmonic and closely related to the phase transitions driven by structural distortion. It remains unclear whether these overdamped modes behave similarly with the soft modes found in oxide perovksites that will harden on warming above phase transition temperature, and how the competition between M and R distortions evolves away from the phase transitions. The different ground state structure of Sn-based and Pb-based halide perovskites may also result in different temperature dependence of the anharmonic phonon modes in cubic phase. We propose to measure CsPbBr3 and CsSnBr3 in high temperature range to reslove these questions regarding their unusual atomic dynamics, which is crucial for further optimization of their optical and thermal properties.

title: Neutron powder diffraction study of the magnetic states in the CeAlSi/CeAlGe family of Weyl semimetals

description: The family of Weyl semimetals present an exciting opportunity to study novel electromagnetic responses, such as the topological and anomalous Hall Effects in response to applied fields. These novel electromagnetic responses have potential applications in a range of novel technologies and as such have received a great deal of interest over recent years. The topological states exhibited by these materials can be tuned by magnetic fields, and also more easily by chemical substitution. In this work, we propose to obtain a set of structural and magnetic data on the substituted Weyl semimetals CeAl(Ge0.7Si0.3), CeAl(Ge0.3Si0.7) and (Ce0.7Pr0.3)Al(Ge0.7Si0.3) in order to understand the magnetic ground states of these topologically interesting materials and understand the precise effect of chemical substitution on their topological magnetism.

title: Spin and lattice dynamics of the high-Tc nickelate superconductor La3Ni2O7

description: The mechanism of high-transition-temperature (high-Tc) superconductivity has been a long-standing question for several decades. Cuprate and iron-based superconductors are two well-known unconventional superconductor families that can shed light on the high-Tc mechanism. In both systems, superconductivity always emerges from the suppression of the antiferromagnetic order in parent compounds by carrier doping or applying high pressure. Nickelates have been proposed to be a promising material platform to search for high-Tc superconductivity due to the structure and electronic structure similarity with cuprates. However, only low-temperature superconductivity in the hole-doped infinite-layer nickelate thin films R1-xAxNiO2 (R = La, Nd, Pr and A = Sr, Ca) has been reported. Recently, we have successfully grown the powder and single-crystal samples of the bilayer nickelate La3Ni2O7 and observed superconductivity with a maximum Tc of 80 K at pressures between 14.0−43.5 Gpa. This observation makes the bilayer nickelate La3Ni2O7 to be a promising candidate of the second unconventional superconducting family with Tc above the liquid nitrogen boiling temperature. INS experiments on this newly discovered high-Tc nickelate superconductor La3Ni2O7 at ambient pressure are thus highly desired for clarifying unconventionality of the superconductivity in La3Ni2O7, which can help to solve the unconventional high-Tc superconductivity mechanism.

title: Photoresponsive wormlike micelles

description: We have been examining photoresponsive materials which change micellar structure on irradiation. Irradiation leads to isomerisation, which then leads to a significant reduction in viscosity, implying a change in the self-assembled structure present. Gentle heating of the solution reverts the molecule to the trans-conformation, with a concomitant recovery of the viscosity. Addition of salts such as NaCl change the overall viscosity of the systems, implying that charge screening is leading to differences in the micellar aggregates formed. Here, we wish to understand these changes and the packing with the micellar aggregates on irradiation and heating.

title: Violation of Superexchange Model in Multiferroic CoCr2O4

description: CoCr2O4 is a multiferroic with a proposed spin-current model dating from the 1960s. However, the model has not been verified due to the lack of data about the spin fluctuations. Our recent neutron spectroscopy experiments show that the exchange is highly frustrated and shows a novel coupling between commensurate and incommensurate spin waves. In order to solve the magnetic exchange parameters unambiguously, we propose to map the complete spin wave dispersion to help gain an understanding of the microscopic origin of ferroelectricity.

title: Magnetic structure analysis of ilmenite-type high-entropy oxide

description: We propose to perform neutron diffraction experiment on the ilmenite-type high-entropy oxide (Mg_0.2Mn_0.2Co_0.2Ni_0.2Zn_0.2)TiO_3 to reveal its magnetic structure. High-entropy oxides containing more than 5 different cations recently attract attention as a novel platform of multifunctional properties. Despite strong cation disorder, some high-entropy oxides have been shown to undergo long-range magnetic ordering. High-entropy oxides have several magnetic cations with different electronic configurations, which may result in bond-disorder in magnetic interactions. Such bond disorder induces frustration, and an appearance of unconventional magnetic properties can be expected. The high-entropy ilmenite (Mg_0.2Mn_0.2Co_0.2Ni_0.2Zn_0.2)TiO_3 displays antiferromagnetic order at 9 K, and frustrated behavior has been discerned in the magnetic susceptibility and specific heat, suggesting the effect of bond-disorder. Therefore, its magnetic structure is of particular interest. We therefore aim to solve the magnetic structure by powder neutron diffraction measurement on high-flux and high-resolution instrument GEM.

title: Polarized off-specular scattering of 11B4C incorporated Fe/Si multilayers for neutron optics

description: For polarizing neutron mirrors it is of utmost importance to investigate the magnetic properties that leads to the polarization, especially magnetic domain sizes that usually are in the order of 1 to 50 µm. In this application, we propose to investigate polarized off-specular scattering of Fe/Si and Fe/Si + 11B4C multilayers to analyze the magnetic domains and how differently they affect the scattering and polarization in the off-specular directions. From pre-studies the 11B4C incorporated Fe/Si multilayers show great potential due to its higher reflectivity, polarization and significant reduction in magnetic coercivity. We believe that the off-specular scattering will be far less for the 11B4C incorporated samples and that we can gain important knowledge from polarization analysis on the off-specularly scattered neutrons to learn about the magnetic domains and its influence on polarization.
