Compensation temperatures and magnetic susceptibility of a mixed ferro-ferrimagnetic ternary alloy

We study the compensation behaviour and magnetic susceptibility of a mixed ferro-ferrimagnetic ternary alloy of the type ABpC1-p on a cubic lattice by the use of Monte Carlo simulations. We consider that the A and X (X=B or C) ions are alternately connected and have different Ising spins SA=3/2, SB=2, and SC=5/2, respectively. In particular, we find that the magnetic susceptibility may exhibit an outstanding behaviour in a vicinity of the critical and compensation temperatures. The relation of the studied model to ternary Prussian blue analogs is also discussed.
