Abstract

X-ray magnetic circular dichroism and resonant photoemission at the Fe and Ni L2,3 edges have been used to investigate the electronic structure of NiFe2O4 (NFO) thin films. The results, when compared to those obtained on Fe3O4, indicate that in a 12 nm NFO film the Ni atoms occupy mainly B sites, as in bulk NFO, and that a decrease in the thickness of the film results in a modification of the nickel hybridization.
