Based on transverse-field Ising model, we investigated the flipping phenomenon of a decorated nanoisland system with spin-1/2 using the decoupling approximation of Fermi-type Green’s function. The results reveal that, under the conditions of relatively weak surface exchange interaction JS/J and transverse-field Ω/J, the system exhibits spin reversal during the heating process. Decorative exchange interaction JD/J only affects the details of the phase transition properties, and the temperature at which spin reversal occurs can still be qualitatively analyzed based on the mean-field phase diagram.
