Annihilation of Vertical-Bloch-line Chains in the First Kind of Dumbbell Domain Walls Subjected to Both Static Bias Field and In-plane Field
摘要/Abstract
摘要:
研究了直流偏场和面内场联合作用下第I类哑铃畴畴壁中 VBL链的消失, 即软化过程 .实验发现, 当直流偏场 Hb>Hsb′时, 第I类哑铃畴的起始软化面内场 (Hip) OHB和临界面内场 Hip′的数值都比不加直流偏场时的数值低, 并且随着直流偏场的增加而减小
Abstract:
Annihi lation procession of verticl-Bloch-line chains in the first kind of dumbbell domainw all subjected to both staticbias field and in-plane field was investig ated ex perimentally. When Hb>Hsb′, it is fo und that the minimum cri tical in-plane field(Hip)OHB and max imum cri tical in-plane fieldHip′w ere both low er than the in-plane field in which the bias field is ignored. Also, the minimum criticalin-plane field(Hip)OHB and maximum critical in-plane field Hip′decrease with the increase of the biasfield.
