Abstract

Vertical Bloch line (VBL) motion in response to the in-plane field pulses was studied by the methods of polarized anisotropic dark field observation (PADO) and high-speed photography in bubble garnets. The mobility of VBLs and their velocities were measured. New types of PADO pictures which are connected with the dynamic changes of VBL and domain wall structures were observed in nonlinear region of Bloch line motion. Difference in the dynamic behavior of VBLs of different types was observed. A qualitative discussion of the origin of PADO contrast features and VBLs behavior difference is proposed.
