Research Abstract

Site-specific configurations of transition metal 3d electrons in spinel ferrites were investigated by electron energy loss spectroscopy (EELS) under electron channeling conditions. In NiFe_2O_4, An electronic difference in the Fe sites caused by ligand field splitting of trivalent Fe was probed. This demonstrated the promise of site-specific valence and spin state analysis in spintronics applications of spinel ferrites.
