论文摘要
在非线性区域的自旋扭转二极管效应上开发了理论分析。得出了通过旋转振荡器产生的二极管电压的分析解，得出了交流电流的整流。二极管电压揭示出非线性取决于振荡器和交流电流之间的相位差。通过对Landau-Lifshitz-Gilbert方程的数值模拟来证实分析预测的有效性。结果表明，旋转二极管效应有助于评估强制同步状态中自旋扭动振荡器的相。
A theoretical analysis is developed on spin-torque diode effect in nonlinear region. An analytical solution of the diode voltage generated from spin-torque oscillator by the rectification of an alternating current is derived. The diode voltage is revealed to depend nonlinearly on the phase difference between the oscillator and the alternating current. The validity of the analytical prediction is confirmed by numerical simulation of the Landau-Lifshitz-Gilbert equation. The results indicate that the spin-torque diode effect is useful to evaluate the phase of a spin-torque oscillator in forced synchronization state.
