摘要

本文讨论了交换偏置柱器件中自旋极化电流驱动磁化开关的微磁模拟。根据交换偏置角的不同，交换可以通过成核过程或自旋的相干旋转发生。对于固定的电流值，相对于易轴以不同角度交换偏置器件显示出减少的开关时间

Magnetization Reversal driven by Spin-Polarized Current in Exchanged Biased Samples

In this paper micromagnetic simulations of magnetization switching driven by spin-polarized current in exchanged biased pillar devices are discussed. Depending on the exchanged biased angle the switching can occurs by means of a nucleation process or by coherent rotation of the spins. For a fixed value of current, exchange biased devices at different angle with respect to the easy axis show a reduced switching time
