Influence of Constant Magnetic Field on Domain Wall Dynamics in YFeO₃

Abstract:

The work presents the experimental results of the dynamics of the domain wall in the plate of yttrium orthoferrite. In our case the speeds of this motion are much less than the speeds of sound in these crystals. A constant magnetic field was oriented parallel to the plate along the domain wall motion and at the angle ≈ 50° to the sample plane and parallel to the plate along the DW motion. We consider forced vibrations of the domain wall under the influence of weak alternating magnetic fields. The domain walls motion was caused by an alternating magnetic field, which was generated by the coils. The effect of the constant magnetic field on the domain wall dynamics has been found.
