研究了具有垂直易轴的CoFeB/ mgo基磁隧道结，通过磁化进动的电场感应磁化开关与外磁场面内分量的关系。开关概率是电压脉冲持续时间的振荡函数，其幅度和周期取决于面内磁场的大小。利用Landau-Lifshitz-Gilbert-Langevin方程将实验结果与模拟结果进行了比较，并讨论了影响概率的可能因素。(C) 2013 AIP出版有限责任公司
Electric field-induced magnetization switching through magnetization precession is investigated as a function of in-plane component of external magnetic field for a CoFeB/MgO-based magnetic tunnel junction with perpendicular easy axis. The switching probability is an oscillatory function of the duration of voltage pulses and its magnitude and period depend on the magnitude of in-plane magnetic field. Experimental results are compared with simulated ones by using Landau-Lifshitz-Gilbert-Langevin equation, and possible factors determining the probability are discussed. (C) 2013 AIP Publishing LLC.
