It is seen that the disorder gives rise to a local molecular field fluctuation acting on a spin in the A sublattice. The temperature behavior of the configuration average of the z component of the spin is presented. © 1979.Mahidol UniversityPhysics and AstronomyArticleSCOPUS10.1016/0375-9601(79)90898-3
