摘要

我们开发了具有结构反转对称性破缺的铁磁性[Co(0.5)/Gd(1)/Pt(1)]N(单位:nm)多层材料，并研究了磁性能和磁畴结构与重复次数(N = 1 - 50)的关系。磁化补偿温度随着N的增加而升高，当N≥20时，磁化补偿温度在210 K左右达到饱和。不同重复次数的薄膜均具有面外磁易轴，且在N = 50的薄膜中观察到剩余物态的多畴结构。这些结果表明，铁磁性Co/Gd/Pt多层膜的磁性可以通过重复次数来调节。

Fabrication of Ferrimagnetic Co/Gd/Pt Multilayers with Structural Inversion Symmetry Breaking

We developed ferrimagnetic [Co(0.5)/Gd(1)/Pt(1)]N (unit: nm) multilayers with structural inversion symmetry breaking and investigated the dependence of magnetic properties and magnetic domain structures on the repetition number (N = 1 – 50). The magnetization compensation temperature increases as N increases, and saturates at around 210 K for N ≥ 20. All films with various repetition number possess the out-of-plane magnetic easy axis, and multi domain structure at the remanence state was observed in the film with N = 50. These results show that the magnetic properties of the ferrimagnetic Co/Gd/Pt multilayers can be tuned by the repetition number.
