Abstract:

We present the comparative study of X-ray absorption spectroscopy (XAS) studies on O K edges of GdFe1−xNixO3 (0≤x≤0.5) and SmFe1−xNixO3 (0≤x≤0.5) samples along with the reference compounds to bestow the exact chemical states of functioning ions. The pre-peaks show the mixing of d states between different atoms, through hybridization with the oxygen p-band. The peaks present the t2g and eg symmetry bands denoting the bare (ionic) crystal field splitting plus hybridization. The XAS studies confirm the complete imbibing of the Ni in the Fe matrix.
