Ferrimagnetism in the Heisenberg–Ising bilayer with magnetically non-equivalent planes
Balcerzak, Tadeusz; Szałowski, Karol - In: Physica A: Statistical Mechanics and its Applications 395 (2014) C, pp. 183-192
The Pair Approximation method is applied to the antiferromagnetic Heisenberg–Ising spin- 1/2 bilayer with a simple cubic crystalline structure. The method allows for self-consistent calculations of thermodynamic quantities, based on the determination of Gibbs free-energy. In the paper the...
