Аннотация

The spectral, temperature, and field dependences of the Faraday effect in the IR spectral range have been studied in single crystals of the CoFe2O4 ferrimagnetic spinel. It is established that the magneto-optical quality factor of CoFe2O4 spinel varies from –60 to +20°/dB in a wavelength range of 1.5–10 μm and weakly depends on the temperature in a 200–300 K interval. Physical mechanisms are proposed that may be responsible for the Faraday effect.
