使用离轴电子全息术和微磁模拟研究了形状为菱形、椭圆形和矩形的图案化亚微米 Co/Au/Ni 纳米结构的层间耦合和磁化反转。由于强 Co 退磁场，铁磁层之间的反铁磁耦合被直接可视化。模拟磁滞回线总体上与实验结果相当一致。局部结构缺陷可能是导致观察到的图案化元件的磁化状态与模拟之间存在微小差异的原因。
The interlayer coupling and magnetization reversal of patterned, submicron Co/Au/Ni nanostructures, shaped as diamonds, ellipses, and rectangles, have been investigated using off-axis electron holography and micromagnetic simulations. Antiferromagnetic coupling between the ferromagnetic layers, attributed to the strong Co demagnetization field, was visualized directly. Simulated hysteresis loops overall showed reasonable agreement with the experimental results. Local structural imperfections may be responsible for small discrepancies between the observed magnetization states of the patterned elements and the simulations.
