Abstract : Magnetooptical properties of the YFeO3, EuFeO3, DyFeO3 and DyIG were investigated in infrared. The nondiagonal components |εÍ| of tensor |ε| are large enough. Faraday Rotation F. R. along optical axis of YFeO3 was estimated from the value |εÍ|. The calculated value of this rotation is equal to 700 °-cm at λ = 1.15 µ. The experimental value is - 600 °-cm. The F. R. in DyIG is isotropic at 80-293 °K and g-factor Dy3+ equals its free ions value. The equation of motion of the magnetic moment with anisotropic g-factor is used for interpretation F. R. at 25 °K.
