Figure 3: Spectral coherence in the synchronized state.

From: Mutual synchronization of spin torque nano-oscillators through a long-range and tunable electrical coupling scheme

Figure 3

(a) Emitted spectral linewidth depending on the magnitude of the DC current injected in the oscillator STO 1 (IDC,2 is fixed to +10.6 mA for STO 2). (b) Phase noise power spectral density in the synchronized state (IDC,2 is fixed to +10.6 mA and IDC,1 is fixed to +11 mA) and in the non-interacting states. The characteristics of each STO when one is switched off are shown in green and orange softened curves).
