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Ho2Co14Fe3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Ho2Co14Fe3磁矩的突变现象。

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.

Key words: Magnetic properties, Exchange interaction, Spin-spin dipole interaction
