摘要: The formation of multi-branched domains( MBDs) at low static bias field was first studied. With multiple branches, MBDs contain more or less same-signed vertical-Bloch-lines (VBLs) in their walls, Experiments. on four samples have shown that under certain conditions, the amount and hardness of the MBDs formed can be easily controlled, and so-called "low-bias-field method" is another effective way to form VBL chains. It was found that MBDs are formed due to the expansion of domain segments after compressed by a rectangular bias pulse. The number of VBLs nucleated in domain walls is affected by the space where the domains expand rapidly.
