The magneto-optical activity and its azimuthal dependence for heteroepitaxial InMnAs thin films were investigated. The longitudinal magneto-optical Kerr effect (MOKE) magnetometry was used for the study of the magneto-optical activity. The films were grown on InAs and GaAs substrates by metallorganic vapor phase epitaxy (MOVPE). The InMnAs films were found to exhibit ferromagnetic magneto-optical activity at room temperature with magnitude of the saturation Kerr rotation of the films ranging from 0.29 to 1.1 mdeg, which varied linearly with respect to the manganese concentration.
