Variational method study of the spin-1 Ising model with biaxial crystal-field anisotropy

J. Ricardo de Sousa, N. S. Branco

The phase diagram of the spin-1 Ising model in the presence of a biaxial crystal-field anisotropy is studied within the framework of a variational approach, based on the Bogolyubov…
