采用直流偏场整形的方法,研究了面内场对石榴石磁泡薄膜中三类硬磁畴的影响.得到面内场作用下三类硬磁畴畴壁中垂直布洛赫线(VBL)是逐步解体的,而且三类硬磁畴具有相同的临界面内场范围[Hi1p,Hi2p],其中Hi1p是硬磁畴中VBL开始丢失时的临界面内场,H2ip是VBL完全丢失时的最小临界面内场.实验结果还揭示了面内场作用下VBL链的解体与硬磁畴的硬度无关,为解释面内场作用下VBL的消失机制提供了重要线索.此外,还为准确测量VBL的临界面内场提供了一种新方案.
The effects of the in-plane field on the three kinds of hard magnetic domains in garnet bubble films were studied by DC bias shaping.The vertical Bloch lines (VBL) of the three kinds of hard-magnetic domains in the in-plane field were obtained, Are gradually disintegrated, and the three types of hard magnetic domains have the same inner critical field [Hi1p, Hi2p], where Hi1p is the critical surface inner field when VBL in the hard magnetic domain begins to lose, and H2ip is the minimum when VBL is completely lost The interfacial interfacial field.Experimental results also reveal that the VBL chain disintegration is not related to the hardness of the hard magnetic domain under in-plane field, which provides an important clue for explaining the disappearance mechanism of VBL under in-plane field effect.In addition, The critical surface infield provides a new solution.
