自旋转移驱动下对称磁性纳米柱的热动力学
Thermal Dynamics in Symmetric Magnetic Nanopillars Driven by Spin Transfer
摘要:
我们研究了自旋转移对磁性纳米柱热激活动力学的影响,磁性纳米柱具有相同的磁性层厚度。对称纳米柱的开关统计特性与磁场和电流具有反常的依赖关系。我们解释我们的数据在同时电流引起的两层激发。我们还发现了由于自旋转移层的波动之间的耦合的证据。
英文摘要:
We study the effects of spin transfer on thermally activated dynamics of magnetic nanopillars with identical thicknesses of the magnetic layers. The symmetric nanopillars exhibit anomalous dependencies of switching statistics on magnetic field and current. We interpret our data in terms of simultaneous current-induced excitation of both layers. We also find evidence for coupling between the fluctuations of the layers due to the spin transfer.
