Probing an electron-spin ensemble with squeezed microwave signals
Fig. 4, panel (d)
Cooperativity C at maximum transfer efficiency, drawn as closely spaced dots against the spin dephasing rate $\gamma_{\mathrm{s}}/2\pi$ and the external coupling rate $\kappa_{\mathrm{ext}}/2\pi$, on the printed 0.2 to 1.0 scale. The $\gamma_{\mathrm{s}}$ values are as deposited, about twice those of the printed curve.
