Popis: The domain wall (DW) velocity versus field dependence in the subsonic range of 0.2–1.1 km/s is studied. The sample is a plate of yttrium orthoferrite YFeO 3 cut perpendicular to the optical axis. The specific Faraday rotation for a wavelength of 0.63 mm equals − 2900 °/cm . A single rectilinear 180° DW was created by applying a quadrupole field. The DW motion was caused by a pulsed magnetic field and analyzed by means of dark-field measurements. Numerous results confirm the nonlinear character of the DW velocity.
