| The magnetic properties of the mixed ferro-ferrimagnetic compounds with (AaBbCc)yD, where A, B, C and D are four different magnetic ions and form four sublattices, are studied by using the standard mean-field theory. In c-a , b-c and
a-b diagrams, the concentration regions of occurrence of two compensation points, and of a compensation point are given, respectively. The phase diagrams of the transition temperature Tc versus a, b and c, and of the compensation temperature Tcomp versus a, b and c are obtained, respectively. The temperature dependences of the magnetization are also investigated. This work is related to experimental works of the molecule-based ferro-ferrimagnet
(NiaIIMnbIIFecII)1.5[CrIII(CN)6]2H2O.
