Fig. 5: Field dependence of the energy gaps.
From: Low-temperature spin dynamics of ferromagnetic molecular ring {Cr8Y8}
The energy gaps obtained from INS and HC data are shown as the black squares and the blue circles, respectively. The Zeeman effect of the low-lying states is evaluated for the single-J model with J = 0.151 meV, as shown as the black and the red lines, which correspond to the splitting of the M levels of the S = 12 ground state and the energy gap between the M = − 12, S = 12 ground state and the M = − 11, S = 11 excited state, respectively. The green dashed line represents the zero-field splitting energy obtained from HC data. The error bars are obtained from the fit with 95% confidence intervals.
