One-Dimensional Ising Model with General Spin

摘要: The one-dimensional Ising model is investigated by generalizing the Bethe approximation, which, in this case, gives exact solutions. energy, specific heat and zero field susceptibility for S =1, 3/2 2 except =2 are calculated exactly compared with results of Suzuki et al. . As a direct application method, special lattice called treated, Curie temperature =1 obtained. This method also applied to solve second neighbor interactions as well first ones, energy =1/2 calculated.
