Stripe-to-bubble Transition of the First Kind of Dumbbell Domains Subjected to Both Static Bias Field and In-plane Field

摘要/Abstract

摘要:

实验研究了直流偏场和面内场共同作用第Ⅰ类哑铃畴(IDs)的条泡转变现象.实验表明:1)存在3个特征直流偏场,即:条泡转变后的磁畴均为软泡的磁场以及条泡转变后的磁畴中依次出现普通硬磁泡和第Ⅰ类哑铃畴的磁场;2)IDs的最小条泡转变面内场和最大条泡转变面内场均随直流偏场的增加而减小.

Abstract:

Stripe-to-bubble transition (SBT)of the first kind of dumbbell domains subjected to both static bias field and in-plane field is studied experimentally .The results suggest that there are three characteristic static bias fields from low to high , i .e , in which the bubble domains transformed from IDs after SBT take place are all soft bubbles (SB), the OHBs and IDs begin to appear in the domains from IDs , after SBT take place .The minimum and maximum in-plane fields of SBT of IDs decrease as Hb increases
