Resonant generation of Bloch lines

An abrupt increase in the density of Bloch lines at a 180° domain boundary was observed in an yttrium ferrogarnet single crystal due to the action of a weak, variable magnetic field, which was directed perpendicularly to the wafer surface and to the magnetization in the domains at certain field amplitudes and frequencies.
