在三层结构中研究了点内层间静磁耦合，该三层结构由两个具有面外各向异性和不同矫顽力的[Co/Pt]多层组成，并由厚的 Pt 层隔开。对于单畴纳米点，强的点内层间静磁相互作用表现为软层磁滞回线的移动。当点的尺寸增加和/或当温度升高时，这种偏移的幅度减小。计算结果和实验结果之间具有令人满意的一致性。
Intra-dot inter-layer magnetostatic coupling have been investigated in trilayers which consist of two [Co/Pt] multilayers with out-of-plane anisotropy and different coercivities separated by a thick Pt layer. For single domain nanodots, the strong intra-dot inter-layer magnetostatic interactions manifest as a shift of the soft layer hysteresis loop. The amplitude of this shift decreases when the size of the dots is increased and/or when the temperature is increased. Satisfactory agreement is found between calculations and experimental results.
