图5 振荡器频谱随外加磁场大小变化的依赖关系：其中（a）和（b）分别为激发电流 $I = 6 ? m A$ 和 $9 ? m A$
The white dotted line in the figure is the dispersion relationship curve of the ferromagnetic resonance frequency f_FMR with the magnetic field,and the f₁ and f₂ represent two types of coherent spin wave modes.

Fig.5 The dependence of the oscillator spectrum with the strength of the applied magnetic field,where the excitation currents $I = 6 ? m A$ (a) and $9 ? m A$ (b)
