“…On the other hand, the two sublattices would tend to align antiparallel under the influence of ferrimagnetic exchange coupling. At the same time, the crystal field D a forces the spins of the sublattice to undergo a flip in a weak h. This triple-loop hysteresis behavior has also been observed in a ferrimagnetic mixed-spin Ising trilayer nanographene superlattice [55] and Heisenberg ferrimagnetic mixed-spin (1/2, 1) structures [56] using the effective-field approach and approximation method, respectively. Most notably, multi-loop hysteresis behaviors have potential utility in multi-state magnetic recording [57].…”

This work focuses on the ground-state phase diagram, the compensation temperatures and critical behaviors of a ferrimagnetic graphene-like trilayer induced by crystal fields and exchange couplings. The simulation results show that a negative decrease in crystal field or an increase in exchange coupling can increase critical temperature. More importantly, the M curve with double compensation temperatures can be observed, which is not predicted in the Néel theory. The remarkable compensation phenomenon has potential application value in the field of magnetic recording.
