Abstract
Due to the demagnetization field of the free layer, an approximate theory was introduced to analyze the synchronization mechanism of coupled nano-oscillators. The necessary conditions of synchronization for a coupled spin-transfer-torque system are derived and dipolar interaction generates synchronization within an induced corrugated attractor. The theory of corrugated attractor also shows that the current feedback effect from Giant Magnetoresistance (GMR) cannot synchronize the second type of spin-torque nano-oscillators. Our theory is consistent with the numerical results from the Landau–Lifshitz–Gilbert equation with a spin-transfer-torque.
