Abstract

âº Pair Approximation is applied to study the S=1/2 magnetic bilayer. âº Anisotropic Heisenberg intraplanar and interplanar couplings are taken into account. âº Thermal behaviour of entropy, specific heat and isothermal entropy change is studied. âº Ising bilayer results are compared with Exact Diagonalization of Finite Clusters. âº A double peak behaviour of specific heat and isothermal entropy change is found.
