The spectral, temperature and field dependences of the Faraday effect for single crystals of ferrimagnetic spinel CoFe2O4 are studied in the infrared range. It is shown that the magneto-optical q-factor of CoFe2O4 varies from -600/dB до +200/dB in the spectral range from 1.5 μm to 10 μm and weakly depends on temperature from 200 K to 300 K. The physical mechanisms responsible for the observed Faraday effect are proposed.
