论文摘要
在没有施加的磁场的情况下，使用相关的Landau-Lifshitz-gilbert-Slonczewski方程的数值模拟研究了带有倾斜偏振器的自旋扭转纳米振荡器（STNO）。我们发现，通过适当地倾斜平面外，我们发现频率的增强。同样，我们观察到振荡频率的可调性从15 GHz到75 GHz，并通过电流和倾斜角度增加功率频谱密度。此外，我们的发现和见解铺平了一种简单的方法，可以实现纳米级级别的微波生成器。
In the absence of an applied magnetic field, a spin-torque nano oscillator(STNO) with a tilted polarizer is studied using numerical simulation of the associated Landau-Lifshitz-Gilbert-Slonczewski equation. We find considerable enhancement of frequency by tilting the polarizer out-of-plane appropriately. Also, we observe improved tunability of frequency of oscillations from 15 GHz to 75 GHz and increment in the power spectral density by current and tilt angle. In addition, our findings and insights pave a simple way for nanoscale level microwave generators to be implemented.
