摘要:
A theoretical analysis has been made of the dynamic behavior of bubble domains when they undergo changes in size or shape. The result of the analysis shows that the changes are characterized by relaxation constants depending primarily on bubble radius, wall mobility, and saturation magnetization. As expected, the perturbations to the domain radius or domain shape are linearly dependent on the magnitude of the various field perturbations and are double valued depending upon whether the field perturbations are increasing or decreasing.
