FORMATION AND STATIC CHARACTERISTICS OF THREE KINDS OF HARD DOMAINS IN BUBBLE MATERIALS
三类硬磁畴的形成及静态特性

The criterion of classification for three kinds of hard domains with lots of VBLS in their walls in garnet bubble materials is proposed. Their formation and static characteristics are described in detail and their typical pictures are shown. Considering the formation conditions of hard domains, it is reasonable to deduce that the increase of the number of VBLs in their walls leads to substantial change of their static characteristics.
