✦ Synopsis

The magnetic properties (phase diagram, compensation temperature, magnetic susceptibility, and magnetization) of the AB p C 1Àp ternary alloy in the presence of a single-ion anisotropy on the B ions only are investigated by the use of a mean-field theory. Depending on the values of the parameters in the model Hamiltonian, the present system may exhibit one, two or even three compensation temperatures T k . It is shown that the total magnetic susceptibility of the ferrimagnetic system can generally take a finite value at transition temperature T c only if the relation T c ¼ T k is exactly satisfied. Also, by using this model, some characteristics observed in the Prussian blue analog of the type ðFe II p Mn II 1Àp Þ 1:5 ½Cr III ðCNÞ 6 Á nH 2 O are quantitatively or qualitatively well reproduced.
