Abstract
A theory of random mixture of antiferromagnetic atoms with different easy axes is developed in which the effect of spin pair correlations is taken into account. A set of integral equations for the distribution functions g (λ) p ( S ) are obtained, where p =A or B atom, λ=α or β sublattice, S is a unit vector pointing to the direction of spin. The integral equations are solved analytically near the transition temperature in the case of small anisotropy and numerically by the computer at low temperatures in general case. The oblique antiferromagnetic phase is clearly recognized.
