The magnetic domain structure modulation in Ni wires deposited on a LiNbO₃ substrate is observed during the application of a DC current or heating. A striped domain structure is formed in the Ni wires that is aligned perpendicular to the X-axis of the LiNbO₃ substrate owing to the competition between magnetic shape anisotropy and uniaxial magnetic anisotropy from the heterojunction. We observe that the striped domain structure disappears as the DC current is increased. In the same manner, it is also confirmed that the striped magnetic domain structure disappears as the substrate is heated. These results are considered to arise from the decrease in uniaxial magnetic anisotropy and magnetization owing to an oxidation reaction at the interface. Heterojunctions are identified to play an important role in controlling and modulating the magnetic properties of this system.

在施加直流电流或加热期间，观察到沉积在LiNbO ₃衬底上的Ni线中的磁畴结构调制。在与LiNbO ₃的X轴垂直对齐的Ni导线中形成条状畴结构由于异质结引起的磁形状各向异性和单轴磁各向异性之间的竞争，导致了基底的形成。我们观察到，随着直流电流的增加，带状畴结构消失了。同样可以确认，随着基板的加热，条纹状的磁畴结构消失。这些结果被认为是由于界面处的氧化反应而导致的单轴磁各向异性和磁化强度降低的结果。异质结在控制和调节该系统的磁性方面起着重要作用。
