Abstract :
The pulse magnetization method was used to study DW (domain wall) dynamics in Tbx(Fe85Co15)100-x amorphous films with Tb content of 18-28 at.%. The films have perpendicular magnetic anisotropy. The character of DW motion was shown to depend significantly on the resultant film magnetization, the amplitude of the pulse magnetic field, and Tb content. The DW mobility was determined to be an asymmetric function with respect to the compensation composition. Critical velocities in the films have not been registered
