N2 - We have investigated the chromium-iron alloy and compared it to the oxides α-Fe2O3 (Eg = 4.8eV) and α-Cr2O3 (Eg = 2.1eV). It is known that α-Cr2O3 and α-Fe2O3 both adopt a corundum-type structure, but display differences in the lattice constants, direct band gap, and magnetic ordering of the cations. The chromium-iron alloy was synthesized by thermal diffusion processes of both chromium and iron thin-films in air atmosphere conditions. We have studied the elastic distortions related to nature of the relative strains as well as magnetic coupling between Fe and Cr from the X-ray diffraction studies.
