Spectrum of excitations of a 180° domain wall containing Bloch lines and points
Kabanov Yu. P., Dedukh L M., Nikitenko V. I.
The spectrum of magnons localized in an isolated 180° domain wall in a YIG single crystal has been studied as a function of the density of Bloch lines and their structure. An induction method and a magnetooptic method were used. A dynamic transformation of the structure of Bloch lines has been observed to result from drift, generation, and annihilation of Bloch points, which cause substantial changes in the characteristics of bending vibrations of the wall.
