X-ray Absorption spectroscopy and electronic structure calculation of DyScO$_{3}$

Dysprosium scandate (DyScO$_{3})$ is of interest for its potential as a substrate for thin film growth of various materials such as EuTiO$_{3}, $SrTiO$_{3}$ BaTiO$_{3}$ and LaSrMnTiO$_{3}$ particularly because it creates biaxial strain due to mismatched lattice constant with those materials affecting their properties. We have used X-ray Absorption Spectroscopy to determine the electronic structure of DyScO$_{3}$. The M$_{4,5}$ edges of Dy and L$_{2,3}$ edges of Sc in DyScO$_{3}$ were investigated against chemically similar materials Dy$_{2}$O$_{3}$ and Sc$_{2}$O$_{3}$ reference powders and compared with theoretical calculations using LCMO multiplet theory. The spectra are well reproduced by calculations with the given atomic structures, an added crystal field and broadening parameters. We find that the Sc L$_{2,3}$ edge in DyScO$_{3}$ is more broadened than in Sc$_{2}$O$_{3}$ and the peak position of Dy M$_{4,5}$ edge in DyScO$_{3}$ is slightly shifted as compared to those in Dy$_{2}$O$_{3}$.
