铁磁金属合金中的内磁场和磁矩

Internal Magnetic Field and Magnetic Moment in Alloys of Ferromagnetic Metals

本文研究了若干晶态和非晶态铁磁金属合金中Fe原子的内磁场和磁矩,认为这些合金中存在两种不同的机制。类金属原子的键合效应和过渡金属原子的电子转移效应,它们导致Fe原子内磁场和磁矩明显降低。所得结果表明,虽然铁磁金属合金中Fe原子的内磁场和磁矩具有同样的变化趋势,但在一般情况下,两者之间不一定存在某种简单的正比关系或线性关系。

In this paper, we investigated the internal magnetic fields and magnetic moments of Fe atoms in several crystalline and amorphous alloys of ferromagnetic metals. It is considered that in these alloys there are two different mechanisms, the bonding effect of metaloid atoms and the electron-migration effect of transition-metal atoms, which obviously decrease the internal magnetic fields and magnetic moments of Fe atoms. The results obtained show that there is not a simple proportional or linear relationship between the internal magnetic field and magnetic moment of Fe atoms in these alloys generally although their variations have a same tendency.
