- Opis:
- Ising mixture with equilibrium disorder is considered. The nearest neighbour spin coupling and direct interatomic interaction are taken into account within two-site cluster approximation. Thermodynamic potential and q-dependent pair correlation function are obtained. Interplay between interspin and interatomic interactions, their influence on magnetic phase transition and alloy segregation are studied. Cluster fluctuations cause significant changes with respect to mean field theory: phase diagram complicates and magnetic properties deviate from those of quenched system.
