Abstract
The Faraday effect in YFeO3 and DyFeO3 was investigated in the wavelength region from 0.6 to 1.8 μ. A gas laser operating at 0.63, 1.15, and 3.39 μ was used. The Faraday rotation in yttrium and dysprosium orthoferrites at the wavelength 0.63 μ is equal to - 3000°/cm and - 4000°/cm, respectively. These values accord with figures calculated from the measurements when light is propagated along the 
axis. The sign of the rotation is opposite to that in YIG. Optical axes lie in the 
plane. The angle between the optical axis of YFeO3 and the axis equals 52° and 46° at the wavelengths 0.63 and 3.39 μ, respectively. The absorption coefficient of the samples used was 200 cm-1at
