对面内场作用下硬磁畴壁中垂直布洛赫线链解体方式的探讨

The Pattern of Break Down of VBL Chains in The Hard Domain Walls. Subjected to an In-plane Field

通过对哑铃畴在面内场作用下自缩泡现象的研究，发现面内场作用下垂直布洛赫线链的解体与哑铃畴在面内场中的位置有关。当哑铃畴与面内场垂直时．其畴壁中的垂直布洛赫线最容易消失，当哑铃畴与面内场平行时，其畴壁中的垂直布洛赫线最难消失。

An experiment was statistically performed on the behavior of the selfshrink bubble of the dumbbel domains subjected to an in-plane field Hip.It was found that the break-down of vertical-Bloch-line is associated with the position of the dumbbell domains in the in-plane field,when the direction of the dumbbell domains is vetical to the orientation of Hip,the VBL in domains wall is eastest to disappear,when the direction of the dumbbell domains is paralled to the orientation of Hip,the VBL in the dimains wall is most difficult to disappear.
