Abstract
The spectrum of magnons localized in an isolated 180-degrees domain wa ll in a YIG single crystal has been studied as a function of the densi ty of Bloch lines and their structure. An induction method and a magne tooptic method were used. A dynamic transformation of the structure of Bloch lines has been observed to result from drift, generation, and a nnihilation of Bloch points, which cause substantial changes in the ch aracteristics of bending vibrations of the wall.
