Current-induced magnetization switching in spin valves

摘要: 通过实验研究了一种特殊的反对称自旋阀结构.研究发现,随着外加磁场的增大,该结构纳米器件表现出了一种由"逆CIMS"向"正常CIMS"的转变.这种现象是因为:该反对称自旋阀在不同的外加磁场下有不同的磁化取向,因而引起不同的CIMS行为.

Abstract: Recently, current-induced magnetization switching (CIMS) behavior in current-perpendicular-to-plane (CPP) exchange-biased spin valve (ESPV) nanopillars has been attracting great attention. In this paper, we experimentally study the C1MS in a special antisymmetrie ESPV structure. With the increase of the external magnetic field, the device shows a transition from inverted CIMS to normal CIMS, which is possibly due to the different magnetic configuration in the antisymmetric ESPV.
