摘要
本文通过研究直流偏磁场Ｈｂ对标称成份为（ＹＳｍＣａ）３（ＦｅＧｅ）５Ｏ１２石榴石磁泡材料中第二类哑铃畴（ＩＤ）长度的影响，观察到：１）ＩＤ的长度随Ｈｂ的升高而缩短；２）经过直流偏场从低到高两次大幅度地准静态升降，ＩＤ长度与Ｈｂ的关系曲线基本重合；３）随着Ｈｂ的升高，直至ＩＩＤ缩灭的过程中，较长ＩＤ与较短ＩＤ的长度比变化不大．这些实验现象暗示。
On the basis of studying the influence of the static bias magnetic field H b on the length l of the second kind of dumbbell domains in the garnet bubble film with the nominal composition (YSmCa) 3(FeGe) 5O 12 , the following phenomena were observed: 1) the length of IID shortenes as H b is increased; 2) after H b is changed for large range two times, the curves l vs H b aproximately coincide; 3) as H b is increased, until IID collapse, the ratio of the longer IID to the short one aproximately equals a constant. These phnomena suggest that the number of VBL in the wall of IID is a constant among the process of the quasistatic change of H b .
