摘要： For the ordinary hard bubbles(OHBs) of garnet bubble films, the annihilation of the vertical-Bloch line (VBL) chains in their walls subjected to joint static bias field Hb and in plane field Hip was experimentally studied. The curves of two critical in-plane fields, H(1)ip and H′ip, vs Hb were measured. By means of the so-called "head-cut" and "tail-cut" experiments designed in this work, it was verified that for the OHBs subjected to Hip, their VBL chains with different lengths lose VBLs and become shorter simultaneously. It was also verified that the critical in-plane fields H(1)ipand H′ip correspond to the break down of the shortest and longest VBL chains of OHBs, respectively.
