摘要:
The energy stored in deformation of a steadily moving domain wall,Wd, is calculated. For a tape sample,Wdper unit area of wall is found to be more than twice the intrinsic energy per unit area of the undistorted wall, &sgr;w. This result raises the question of whether it is meaningful to speak of the wall energy density in a thin film when the stored energy may fluctuate drastically.
