Abstract

The electronic structure of La_1-xSr_xCoO₃ has been studied by photoemission and x-ray absorption spectroscopy. The valence-band spectra for LaCoO₃ show features characteristic of the low-spin state. The spectra systematically change with x, showing a gradual transition from the low-spin to high-spin states. The difference between the on- and off-resonant photoemission spectra shows small but detectable changes, corresponding to the magnetic transition. The absence of significant changes with temperature in the valence-band spectra of La_0.6Sr_0.4CoO₃ clearly demonstrates a distinction between the Co and Mn perovskites.
