论文摘要
这封信报告了磁性绝缘体Y3FE5O12在相邻拓扑绝缘子BI2SE3薄膜中的磁性修饰。铁磁共振测量表明，BI2SE3中的TSS产生垂直磁各向异性，导致旋转磁比的降低，并增强Y3FE5O5O12的阻尼。随着温度从300 K降低到50 K，这种TSS引起的变化变得更加明显。这些结果表明，一种全新的方法可以控制磁性薄膜中的磁性。
This letter reports the modification of magnetism in a magnetic insulator Y3Fe5O12 thin film by topological surface states (TSS) in an adjacent topological insulator Bi2Se3 thin film. Ferromagnetic resonance measurements show that the TSS in Bi2Se3 produces a perpendicular magnetic anisotropy, results in a decrease in the gyromagnetic ratio, and enhances the damping in Y3Fe5O12. Such TSS-induced changes become more pronounced as the temperature decreases from 300 K to 50 K. These results suggest a completely new approach for control of magnetism in magnetic thin films.
