Direct Electron Spectroscopy Investigation of the Spin State of LaCoO$_3$

ORAL

Abstract

The spin state of LaCoO$_3$ and related properties have been a topic of high interest lately. Here we investigate the electronic structure of LaCoO$_3$ using core level and valence band photo-electron spectroscopy. We compare the competing spin models in the literature by using our data obtained as a function of incident photon energy and temperature. We are able to make an interesting contribution to the discussion of the spin state of this material.
