摘要： Experiments were statistically carried out on the behavior of vertical-Bloch-line(VBL) chains in the walls of the second kind of dumbbell domains (IIDs) is garnet bubble films subjected to joint action of static bias field Hb and in-plane field Hip. The curves of the four critical in-plane fields, (Hip)IID-ID (Hip)IID-OHB (Hip)IID-SB and H'ip vs Hb were measured and explained. In particular, in terms of two series of IID photos, a new experimental manifestation of the unknown "number effect" of VBL chains was found.
