Abstract :
Summary form only given. The weak ferromagnetic orthoferrites (RFeO3) are often investigated with regards to domain wall (DW) motion. This paper is a report about the experimental detection of peculiarities in DW dynamics, which are explained by self-organization. The values of supersonic velocities are found, from which the discrete transitions from a stationary to non-stationary DW motion are observed for TmFeO/sub 3/ samples. At these velocities the DW form becomes multidimensional.
