Abstract

The influence of disorder in the cation sublattice on the magnetic properties of 1: 1 double perovskites is investigated in the framework of the Heisenberg model. It is revealed that the dependence of the sublattice magnetization on the degree of atomic ordering for strontium ferromolybdate exhibits a linear behavior. The results of simulation allow the assumption that disordered lead ferroniobate has a spin-glass structure.
