Electronic structure of pristine and Ni-substituted LaFeO${}_3$ from near edge x-ray absorption fine structure experiments and first-principles simulations

Iurii Timrov, Piyush Agrawal, Xinyu Zhang +7

We present a joint theoretical and experimental study of the oxygen $K$-edge spectra for LaFeO${}_3$ and homovalent Ni-substituted LaFeO${}_3$ (LaFe${}_{0.75}$Ni${}_{0.25}$O${}_3$), using fi…
