Abstract

Abstract—

The article studies the magnetic properties of the Fe_{1 –} _xZn_xCr₂S₄ alloy using the method of random fields of exchange interaction. The critical concentrations are determined at which a transition from the ferrimagnetic state to the spin-glass state (x = 0.66) is observed, followed by a transition to the antiferromagnetic state (x = 0.99). A magnetic phase diagram is constructed, which compares the results of calculation with experiment.
