Phys. Rev. B 55, 6356–6359 (1997)Testing a simple criterion for the critical temperature
We investigate the applicability of a simple criterion proposed by Wosiek [Phys. Rev. B 49, 15 023 (1994)] for locating analytically critical temperatures; we apply it to Ising-like spin models with anisotropic interactions, more than one type of interaction between the spins, and multiple-spin interactions. The predicted critical temperatures only agree with the known exact results or with Monte Carlo simulations for very particular, highly symmetrical values of the coupling constants. © 1997 The American Physical Society URL:
