摘要

在传递矩阵法的框架下，对自旋-s一维Ising模型进行了分析研究。在没有(存在)磁场的情况下，得到了一般自旋s的热力学性质，如内能、熵、磁化率和磁化率的精确结果。分析了不同温度和不同场下自旋s(1/2、1和3/2)值的热力学性质的临界行为。研究了这些性质在接近临界温度T→0和T→∞时的渐近性态。

On the critical behavior of the spin-s Ising model

The spin-s one dimensional Ising model is studied analytically within the framework of transfer matrix method. Exact results for some thermodynamical properties such as the internal energy, the entropy, the magnetization and the magnetic susceptibility are obtained for general spin-s in the absence (presence) of a magnetic field. The critical behavior of the thermodynamical properties are analysed for some values of spin-s (1/2, 1 and 3/2) at different temperature and field. The asymptotic behavior of these properties are investigated especially close to the critical temperature T → 0 and when T → ∞.
