Study on dynamic magnetic characteristics of a bilayer graphdiyne-like nanoribbon

Graphdiyne-like nanoribbons are promising for information retrieval, storage, and magnetic refrigeration due to their excellent magnetic and thermodynamic properties. In this paper, we build a ferrimagnetic mixed-spin (2, 5/2) Ising model for the bilayer graphdiyne-like nanoribbon. The instantaneous magnetization, dynamic order parameter, magnetic susceptibility, phase diagram, and dynamic hysteresis loops are studied induced by the exchange coupling, crystal field, and amplitude and period of the time-oscillating magnetic field [Formula: see text]. The analysis reveals that the decrease in both amplitude and period field of [Formula: see text] leads to an increase in the critical temperature [Formula: see text] of the system. Under certain values of the crystal field, the compensation-temperature behavior and the double-peak phenomenon of the magnetic susceptibility curve can be observed. Decreasing the amplitude of [Formula: see text] leads to an increase in the [Formula: see text] of the system. In addition, the system exhibits rich multi-loop hysteresis behaviors under certain Hamiltonian parameters.
