直流偏场和面内场作用下ID畴壁中VBL链的消失

Annihilation of Vertical-Bloch-line Chains in the First Kind of Dumbbell Domain Walls Subjected to BothStatic Bias Field and In-plane Field

研究了直流偏场和面内场联合作用下第 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 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 。

Annihilation procession of verticl Bloch line chains in the first kind of dumbbell domain wall subjected to both static bias field and in plane field was investigated experimentally.When H b> H sb ′,it is found that the minimum critical in plane field( H ip ) OHB and maximum critical in plane field H ip ′ were both lower than the in plane field in which the bias field is ignored.Also,the minimum critical in plane field( H ip ) OHB and maximum critical in plane field H ip ′ decrease with the increase of the bias field.
