摘要
We study the velocity versus applied-field relation of a moving Bloch domain wall, using the collective-coordinate method employed in the theory of soliton motion. For a sufficiently large field, the wall emits spin waves, thereby self-limiting its velocity. That velocity is equal to the common value of the phase and group velocities of a particular spin wave, and may be above or below the Walker limit VW, depending on the intrinsic damping. © 1990 The American Physical Society.
