Stability of Spin-Torque Oscillators With Dual Free Layers

A system of differential equations describing the stability of a spin-torque oscillator (STO) with two free layers is introduced. The system is derived from the Landau-Lifshitz-Gilbert (LLG) equation for two freely rotating magnetic moments interacting via spin-torque. In the case of two free magnet...
