对非线性区下的单自旋力矩振子进行了数值研究。大角度进动触发多个模式的生成，而没有任何反馈电路和/或与相邻振荡器的磁耦合。我们的模拟表明，一个给定的自旋力矩振荡器的一个本征模可以触发多达六个离散模式的边带模式。这些发现将为STO提供新的功能，用于开发自旋电子逻辑电路。
A numerical investigation is conducted for a single spin-torque oscillator 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 spin-torque oscillator 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.
