| 摘 要： | 利用迭代方法,在亚铁磁情况下,研究了晶体场作用下二重Cayley树上自旋为1/2和3/2的混合Ising模型的热力学和临界现象.通过数值求解,得出了亚晶格磁化强度MA,MB和系统总磁化强度肘随温度变化的曲线,并和铁磁情况所得结果进行比较.研究发现,子晶格B上的磁化强度MB随温度变化的趋势与铁磁情况下一致,而对于子晶格A来讲,磁化强度MA]随温度变化的趋势与铁磁情况下一致,同时得出总磁化强度M的变化趋势与亚晶格磁化强度MA的变化一致,而且配位数对MA的随温度变化的曲线产生影响.结果发现,亚铁磁情况下该系统不存在三临界行为.

| Abstract: | Using the recursion method,the phase transition and the thermodynamic behavior of the mixed spin-12 and spin-32 Ising system on the two-fold Cayley tree are studied for the ferrimagnetic case.For the ferrimagnetic case,the relations of sublattice magnetizations MA,MB and the total magnetization M with the temperature are obtained,respectively.It is found that the behavior of M is similar to that of MA.The behavior of MB is agree with that of the ferromagnetic case,but the behavior of |MA| is consistent with... |
