Abstract

We report on the investigations of the magnetic properties and ferromagnetic resonance in the heterostructure consisting of an epitaxial yttrium iron garnet (Y₃Fe₅O₁₂) film and a nanometer rare-earth intermetallic superlattice comprised of the (TbCo₂/FeCo)_n exchange-coupled layers. The (TbCo₂/FeCo)_n superlattice exhibits the giant magnetostriction and the controlled magnetic anisotropy induced by a magnetic field or elastic stresses. The magnetic interaction of the films in the (TbCo₂/FeCo)_n/Y₃Fe₅O₁₂ heterostructure has been experimentally established and the spin current flowing through their interface has been detected.

铁磁性钇铁石榴石薄膜/铁磁性金属间化合物异质结构中的铁磁性

摘要

我们报告了由外延钇铁石榴石（Y ₃ Fe ₅ O ₁₂）膜和由​​（TbCo ₂ / FeCo）_n交换组成的纳米稀土金属间超晶格构成的异质结构中的磁性和铁磁共振研究耦合层。（TbCo ₂ / FeCo）_n超晶格表现出巨大的磁致伸缩和由磁场或弹性应力引起的受控磁各向异性。（TbCo ₂ / FeCo）_n / Y ₃ Fe ₅ O _12中薄膜的磁相互作用 已经通过实验建立了异质结构，并且已经检测到流过它们界面的自旋电流。
