| Abstract: | Computer simulation is an effective method for studying the VBL motion along the domain wall in Garnet film. Coupled dsrivative equations for domain wall motion derived by Slonczewski are solved numerically by the finitedifference method. The 2-dimensional boundary conditions and static wall structure with vertical Bloch line (VBL) are described. The effects of VBL potential well on domain wall and VBL propagation are discussed. It is shown that the amplitudes of both the potential well and pulse bias field should be carefuuflly considered for VBL to propagate along the domain wall bit by bit. |
