| 摘 要： | 将 Salzberg 等发展的低温 Bethe 格点方法进行了自洽修正后推广到了整个温区,计算了稀磁合金 A_xB_(1-x)(其中A为磁原子,自旋为S,B为非磁原子,自旋为零)的局域磁矩,居里温度和磁化率。结果表明,自洽 Bethe 格点方法改进了分子场理论近似,所得结果比较可靠,它适用于研究实际稀磁合金的磁学性质。

| Abstract: | After making a self-consistent correction,extends the low-temperature Bethe lattice method developed by salzberg et al to the whole range of temperature and calculate some physical quantities of diluted alloy ArB1-x(where A is a magnetic atom with spin S and B a non-magnetic atom with null spin), such as local magnetic moment. Curie temperature and susceptibility. The results show that the self- consistent BL method can improve theoretically the approximation of molecular field with reliable results provided,also available to the study on the magnetic properties of diluted alloys. |
