A numerical investigation is conducted for a single spin-torque oscillator (STO) under the non-linear region. A large angle precession triggers the generation of multiple modes without any feedbacked circuits and/or magnetic couplings with neighboring oscillators. Our simulations show that a single eigenmode of a given STO can trigger up to six discrete modes as the sideband modes. These findings will offer the new functionality to the STO for developing the spintronic logic circuits.

非线性区域下单个自旋转矩振荡器的多种模式

对非线性区域下的单个自旋转矩振荡器（STO）进行了数值研究。大角度进动可触发多种模式的产生，而无需任何反馈电路和/或与相邻振荡器的磁耦合。我们的仿真表明，给定STO的单个本征模式可以触发多达六个离散模式作为边带模式。这些发现将为STO提供开发自旋电子逻辑电路的新功能。
