【摘要】 在分析稀土磁性常用的哈密顿中，引入了自旋－自旋偶极作用，用参数拟合的方法对Ｈｏ_２Ｃｏ_１４Ｆｅ_３的磁化曲线进行了分析，计算结果与实验数据符合得很好，并且揭示了Ｈｏ_２Ｃｏ_１４Ｆｅ_３磁矩的突变现象。更多还原

【Abstract】 By adding the spin-spin dipole interaction in the convention Hamiltonian,a theoretical analysis of the experimental magnetization of rare earth compound Ho2Co14Fe3 is performed with the aid of parameter-fitting method.It is shown that when the theoretical parameters are adequately fixed,the calculated magnetization curve is in agreement with that ofthe magnetic experiments,and the transition of magnetic moment is explained.更多还原
