We study the electronic structure and magnetic properties of epitaxial (Ni $_{1-x}$ Co $_{x}$ )Fe $_{2}$ O $_{4}$ (111) layers with thicknesses = 1.7 - 5.2 nm grown on Al $_{2}$ O $_{3}$ (111)/Si(111) structures. We revealed the crystallographic (octahedral $O_{h}$ or tetrahedral $T_{d}$ ) sites and the valences of the Fe, Co, and Ni cations using experimental soft X-ray absorption spectroscopy and X-ray magnetic circular dichroism spectra and configuration-interaction cluster-model calculation.
