Abstract
Recent measurements of the Faraday rotation in the visible and near infrare d spectral region on the copper ferrite films prepared by the sputtering me thod showed the anomalous behavior of rotation at 1.8 mum wavelength. Suppo sing the presence of Cu2+ ion on the A site under the cubic crystal field V (T-d), the spin-orbit coupling zeta (l . s), the low symmetry crystalline f ield V(S-4), and the molecular field AS(z)[S-z(Fe)] from the iron spin [S-z (Fe)], we can calculate the line shape of the observed anomaly.
