Temperature dependent XAS of FePS3 compound

In 2D antiferromagnetic MPS3 compounds – M is a 3d transition metal – the correlation between spin and orbital excitations often leads to strong coupling between the electronic transitions and the lattice magnetic order. Unlike other members of the family, no evidences have been reported up to now for FePS3, despite the higher magnetic moment of iron. Our preliminary Resonant Inelastic X-ray Scattering (RIXS) measurements at the Fe L3 edge show indications of a possible correlation between dd electronic transitions and magnetic excitations, also supported by simulations. However, accurate knowledge of the absorption behavior below and above the Neel temperature as well as of the homogeneity of the sample are preliminary to analyze RIXS data. To this purpose we aim to study the temperature dependence of XAS in FePS3 between 20 and 200K.
