| 摘 要： | 实验研究了立方磁晶各向异性对面内场作用下非压缩状态的三类硬磁畴（普通硬磁泡（OHB）、第Ⅰ类哑铃畴（ID）和第Ⅱ类哑铃畴（IID））畴壁中垂直布洛赫线（VBL）的影响,发现对应于垂直布洛赫线消失的临界面内场的数值变化与磁畴消失场的数值变化规律相反,且该临界面内场的变化呈六重对称性。此外,发现立方磁晶各向异性对垂直布洛赫线消失的临界面内场的影响很小。

| Abstract: | The influence of cubic crystalline anisotropy on the hard domain under in-plane field was investigated experimentally.It was found that the critical in-plane fields change periodically when the crystal direction changes in plane,and their changes are opposite to the domain-erasing field.A six-fold symmetry of the critical in-plane field in the sample plane was observed.Applying in-plane field in different directions,the influence of crystal direction on the annihilation of VBLs in hard domain walls is only ... |
