采用与c轴成一定角度切割Nd-Fe-B烧结磁体的方法，研究了磁体底部磁化对磁体表面磁畴结构的影响。当表面与c轴的夹角大于30度时，由于表面退磁场的增加，观察到的磁畴结构变为迷宫状。相反，当切割角为10度时，剩余磁化强度随着所施加的场而增加。结果发现，在10度的切割角，下面的磁畴配置可以通过从下面的晶粒的磁通量的传播，通过表面间接观察。
The influence of underneath magnetization of Nd-Fe-B sintered magnets on surface domain configurations was investigated using a Kerr microscope by cutting the magnets at an angle to the c-axis. When the angle formed by the surface and the c-axis is larger than 30 degrees, the observed domain configurations change to maze patterns because of an increase in the demagnetizing field at the surface. In contrast, when the cutting angle is 10 degrees, residual magnetization increases with the applied field. It was found that at a cutting angle of 10 degrees, the underneath domain configurations can be indirectly observed through the surface by propagation of magnetic flux from the underneath grains.
