研究了面内磁化铁磁体自旋矩开关势垒与电流的关系。引入两个标度电流I-c和I-c（> I-c）来区分磁化稳定性。在低电流区域I < I-c中，开关势垒与具有另一缩放电流I-c的电流成线性关系，而这种线性缩放在高电流区域I-c中不成立
The current dependence of the switching barrier for spin torque switching of an in-plane magnetized ferromagnet was studied. Two scaling currents, I-c and I-c (> I-c), were introduced to distinguish the magnetization stability. In the low-current region I < I-c, the switching barrier is linear to the current with another scaling current I-c, while such linear scaling does not hold in the high-current region I-c
