| 摘 要： | 实验研究了一次脉冲偏场作用下外延石榴石膜硬磁泡的形成规律。通过实验和计算,证明了硬泡畴壁中同号的VBL一般地说并非一个脉冲产生一对。通过双重曝光照相法揭示出软畴段的硬化与畴段运动形式的关系,发现了最适于硬泡形成的两种运动形式,并阐明了“软硬磁泡形成的分界场”Hb]的物理意义。

| Abstract: | The formation of hard bubbles by single-pulse bias field in epitaxial garnet films was investigated in some detail. It was verified by experiments and calculations that, in general, VBL in hard bubble walls are not generated by the way that one Bloch line pair is produced per pulse. The dependence of the hardening of soft domain segments on their movements was revealed by means of the method of double exposure photography. Two kinds of favorite movements for hard bubble formation were discovered and the physical meaning of the" demarcation field for soft and hard bubble formation" Hb] was elucidated. |
