Temperature-dependent soft x-ray photoemission and absorption studies of charge disproportionation in La${}_{1-x}$Sr${}_x$FeO${}_3$

H. Wadati, A. Chikamatsu, R. Hashimoto +7

We have measured the temperature dependence of the photoemission and x-ray absorption spectra of La${}_{1-x}$Sr${}_x$FeO${}_3$ (LSFO) epitaxial thin films with $x=0.67$, where charge dis…
