The solid solutions between ilmenite and hematite have recently attracted considerable attention as a spintronic material due to their interesting magnetic and electrical properties. In this study, the electronic and magnetic structures of epitaxially grown ilmenite-hematite solid solution thin films were investigated by combining X-ray absorption near-edge structure (XANES), X-ray magnetic circular dichroism (XMCD) for two different crystallographic projections, and first-principles theoretical calculations.
