Supercritical velocities of domain walls in orthoferrites
Chetkin M.V., Akhutkina A.I., Shalygin A.N.
Record high velocities of a domain wall were obtained in yttrium orthoferrite as high as 6χ106 cm/sec, or three times larger than the critical velocity. Motion of a domain wall with superlimiting velocity reveals a nonstationary behavior that develops at a distance on the order of 0.5 cm.
