Abstract :
Recent measurements of the Faraday rotation in the visible and near infrared spectral region on the copper ferrite films prepared by the sputtering method showed the anomalous behavior of rotation at 1.8 μm wavelength. Supposing the presence of Cu2+ ion on the A site under the cubic crystal field V(Td), the spin-orbit coupling ζ(l.s), the low symmetry crystalline field V(S4), and the molecular field ASx⟨Sx Fe⟩ from the iron spin ⟨SxFe ⟩, we can calculate the line shape of the observed anomaly
