title: Investigation of the magnetic ground state of non-collinear antiferromagnet Mn3NiN

description: Spintronic devices utilising ferromagnets for memory applications are nearing their performance limits. An innovative approach to overcome these constraints involves using non-collinear antiferromagnets (NCAFMs). NCAFMs have garnered considerable interest due to their unique advantages, including ultrafast spin dynamics and higher packing densities resulting from minimal stray magnetic fields, making them superior to ferromagnets. During this beamtime, we focus on investigating Mn₃NiN, a key material within the NCAFM family. The small net moment in this material will allow the stabilisation of the single domain state, leading to a finite anomalous Hall resistivity, which can be detected electrically. While theoretical predictions suggest that the antiferromagnetic ground state of Mn₃NiN is driven primarily by the Mn atoms' contributions to the total magnetic moment, our previous measurements using X-ray magnetic circular dichroism (XMCD) have revealed a more complex magnetic structure. Specifically, we have observed finite magnetic moments not only from Mn atoms but also from Ni atoms, which challenges the conventional understanding of the material's magnetic ordering. To further investigate this, we plan to conduct experiments on Mn₃NiN samples with varying Ni concentrations, systematically analysing how Ni influences the overall magnetic moment of the system. By carefully evaluating the role of Ni, we aim to refine our understanding of the magnetic interactions within Mn₃NiN and potentially uncover new insights into the magnetic behaviour of NCAFMs.

title: 1D chiral edge modes in a van der Waals heterostructure

description: We have fabricated a novel heterostructure combining a ferromagnetic layer of CrCl3 with a superconducting substrate of NbSe2. This system is particularly promising for investigation of the proximity-induced superconductivity with potential application in future quantum technology. Our initial experiments using low-temperature scanning tunneling microscopy and spectroscopy have revealed the presence of chiral 1D edge modes along the boundary of the CrCl3 island, while the bulk of the material exhibits a gapped superconducting state induced by proximity to NbSe2. Initial theoretical calculation suggests that such 1D chiral edge mode can only survive in presence of the ferromagnetic ground state of CrCl3 with perpendicular magnetic anisotropy. We have previously demonstrated that CrCl3 on Graphene is a 2DXY ferromagnet which challenges our initial experimental findings. It's important to consider that the proximity effect between CrCl3 and graphene might differ significantly when NbSe2 is used instead, due to its stronger spin-orbit coupling. Therefore we would like to carry out XMCD measurement to explore how the proximity effect between CrCl3 and NbSe2 affects the magnetic anisotropy axis and transition temperature of CrCl3.

title: Twisted magnetic van der Waals structures investigated with XMCD and coherent imaging

description: Stacking engineering opens the door to the controlled breaking of different symmetries of a condensed matter system, enabling novel electronic and magnetic properties. For instance, parallel stacking of different pieces of the same crystal has the potential to enable the emergence of ferroelectric order, and twisted stacking of magnetic and even non-magnetic 2D materials allow for emerging magnetic properties and asymmetric magnetic exchange interactions, and altogether, multiferroicity in van der Waals materials. We are working on achieving some of these emergent properties in twisted samples of the Fe3GeTe2 family, and propose to investigate them with XMCD and coherent imaging, enabling to look at magnetic properties at the atomic level and with nanoscale resolution.

title: Investigating emergent magnetic and electronic phenomena in oxide heterostructures using X-ray absorption spectroscopy

description: The study of oxide heterostructures has revealed emergent quantum phenomena arising from interfacial electronic and magnetic interactions. In this work, we investigate the anomalous Hall effect (AHE) in [(CaRuO₃)/(SrIrO₃)]₁₀ superlattices, where individual bulk components are non-magnetic but exhibit intriguing interfacial magnetism. Using pulsed laser deposition, we successfully fabricated epitaxial superlattices with precise control over layer thickness, revealing a systematic thickness-dependent magnetic anisotropy. To probe the underlying electronic and magnetic structure, we propose X-ray absorption spectroscopy (XAS), X-ray linear dichroism (XLD), and X-ray magnetic circular dichroism (XMCD) measurements at Ru and Ir edges. These techniques will provide element-specific insights into charge transfer, orbital hybridization, and spin-orbit coupling effects at the interface. Our results will enhance the understanding of interfacial magnetism and quantum transport in oxide heterostructures, with potential implications for future spintronic applications.

title: Temperature dependent EXAFS study on LiNiO2 cathode for improved applications

description: Battery applications such as electric vehicles request high energy densities. In this context, layered LiNiO2 (LNO) cathode could contribute with the highest specific capacity in the LiNi1−x−yCoxMnyO2 (NCM) family. To achieve high capacities requires a defect free crystal structure, which is not easily achieved due to the natural occurrence of Ni excess on the Li site and/or anti-site defects where Ni and Li switch crystallographic sites. The amount of excess of nickel should be small to obtain a large rechargeable capacity, while the oxygen loss is widely recognized as a major factor in the structural degradation of Ni-rich layered cathode materials. A study on the role of the inevitable Li/Ni disordering defects is still lacking, and is the focus of the present proposal. Our aim is to characterize the evolution of the Ni electronic and local structural properties by means of Ni K-edge temperature dependent XAS study on a set of LiNiO2 cathodes with well characterized different Li+/Ni2+ mixing. We will focus on the effect of the Li+/Ni2+ mixing on the local electronic and structural properties. This approach will allow addressing fundamental electronical and structural aspects that define the functional properties of Ni-rich cathode materials for Li-ion batteries.

title: Investigation of Spin State of Mn3+ in Corrugated Zigzag O3-NaMnO2 cathode in the Sodium-ion Batteries

description: Rechargeable sodium-ion batteries are promising for large-scale energy storage owing to the abundance of sodium and its low cost1. O3-NaMnO2 type layered transition metal oxides have received great attention due to their high theoretical specific capacity (265 mAh g-1), cost benefits and sustainable resource supply. Nevertheless, the local Mn3+ John-Teller (J-T) distortion will trigger co-operative J-T followed by structural collapse, leading to the loss of reversible capacity upon Na+ extraction/insertion in α-NaMnO2 (monoclinic)2. According to the ligand field theory, the Mn3+ ions in the octahedral ligand (MnO6) appear as high-spin (t2g3eg1, S = 2) and low-spin (t2g4eg0, S = 1) ions, respectively. The high-spin Jahn-Teller (J-T) Mn3+ ion is one of the reasons for the severe structural degradation and voltage decay of the Mn-based layered materials. Here, we propose mitigate severe co-operative J-T distortion by employ the β-NaMnO2 form (orthorhombic) as cathode which is distributing the strain more evenly across the crystal lattice3. However, the electrochemical performance remains unsatisfactory. Here, we introduce high-valence Nb into the Mn site of β-NaMnO₂ to optimize the local coordination environment and reduce lattice strain energy, thereby stabilizing the structure. Despite these efforts, the mechanisms underlying Mn3+ spin state, voltage decay and structural degradation of β-NaMnO₂ during cycling remain largely unexplored. This work aims to investigate the Mn3+ spin state evolution, voltage decay mechanism and structure evolution of β-NaMnO₂ using advanced X-ray Magnetic Circular Dichroism (XMCD), complemented by operando X-ray diffraction (XRD) and pair distribution function (PDF) analysis, to deconvolute the key factors contributing to Mn3+ spin state evolution. Concerning the long-standing analytical challenge in characterising the Mn3+ spin state which related the J-T distortion, XMCD would be critical to gaining insights into these materials degradation mechanism to establish their structure-property relationship for further performance enhancement.
