From: Efficient Synchronization of Dipolarly Coupled Vortex-Based Spin Transfer Nano-Oscillators
(a) Illustration of the synchronized motion of the two auto-oscillating vortices cores and of their net in-plane magnetizations (black arrows), for the cases of identical polarities (left) and opposite polarities (right) during one period. The sign of the associated dipolar coupling energy Wint is also given. (b) Predicted evolution of the dipolar coupling energy Wint versus part of oscillation period for identical (blue) and opposite polarities (red). The dotted lines show the average interaction energy in both cases.
