论文摘要
提出了基于磁各向异性（VCMA）电压控制的低功率磁化开关方案。与使用VCMA的常规开关方案相反，VCMA在电压脉冲过程中消除了磁各向异性，磁各向异性得到增强，以诱导靠近易于轴的轴周围的进攻。在近距离预动力期的一半近距离关闭电压后，磁化放大向相反的平衡方向。我们执行数值模拟，并表明所提出的开关方案的脉冲持续时间短达几十秒。由于焦耳加热减少了能量损失，因此如此短的脉冲持续时间对低功率消耗有益。
A low power magnetization switching scheme based on the voltage control of magnetic anisotropy (VCMA) is proposed. In contrast to the conventional switching scheme using VCMA, where the magnetic anisotropy is eliminated during the voltage pulse, the magnetic anisotropy is enhanced to induce precession around the axis close to the easy axis. After turning off the voltage proximately at a half of precession period, the magnetization relaxes to the opposite equilibrium direction. We perform numerical simulations and show that the pulse duration of the proposed switching scheme is as short as a few tens of pico seconds. Such a short pulse duration is beneficial for low power consumption because of the reduction of energy loss by Joule heating.
