intralayer coupling constants of the two layers (J1,J2), interlayer coupling constant between the layers (J3) and crystal field … diagrams of the model are obtained on the (J2/|J1|,J3/q|J1|) plane with J1>0 for given crystal field values. Then, the phase … diagrams of the system are obtained on the (kT/J1,J3/J1) planes for given values of the crystal field and α=J2/J1 on the …
