EXPERIMENTAL-STUDY OF EXCITATION SPECTRUM OF A DOMAIN-WALL WITH BLOCHLINES IN YTTRIUM-IRON-GARNET SINGLE-CRYSTAL

Using an inductive method it is possible to reveal and study the flexu ral vibrations of Bloch lines in an oscillating domain wall. The depen dence of flexural eigenvibrations of a 180 degrees domain wall on the Bloch-line density is studied for the first time. The fine structure o f the spectrum of the eigenvibrations of the wall containing Bloch lin es is found. It is shown to be caused, in particular, by eigenvibratio ns of Bloch lines.
