Fig. 7. (a) HYSCORE performed at 5 K and g‖ spectral position for 1.0C60@Cu0.1-PCN-223 plotted after data processing. (b) Rabi oscillations recorded for 1.0C60@Cu0.1-PCN-223 at 20 K and g‖ spectral position applying various microwave power attenuation. (c) Fast Fourier transform (FFT) of the Rabi oscillations with an asterisk denoting Larmor frequency of proton spins ≈13.5 MHz while arrows denote Rabi frequencies. (d) Linear dependence of the Rabi frequency, νR, as a function of the oscillating microwave field, B1, calculated according to ref. 63 and 64.
