摘要: The softening process of the second kind of dumbbell domalns(liDs) in garnet bubble films subjected to an in-plane field Hip at different static bias field Hb was studied experimentally. It was found that when Hb is larger, the remaining percentage of IID, RIID, drops sharply at a certain Hip, and with the increase of Hb the drop occurs at lower Hip and becomes more intensive. We have confirmed that this is related to the "spontaneous-shrink" 0f IIDs, which plays an important role for the breakdown oF vertical Bloeh line chains of lids subjected to joint fields Hip and Hb .
