| Abstract: | A method which combines the two - site cluster approximation and the discretizedpath - integral representation (DPIR) is proposed to study thermodynamic properties of ferromagnetic superlattice consisting of two alternating materials, which is described by simple spin - 1/2 transverse Ising model. The dependence of the critical temperature of superlattice on the geometric structure and the coupling strengths in the interface and bulk layers is studied. The dependence of the spontaneous magnetiztion on the temperature is also studied. |
