用液态快淬法制备非晶合金条带时,通过加入15—30％的B与Si等类金属含量是形成非晶状态的必要条件。但是,由于Si与B等类金属元素的加入,使非晶态合金的磁性受到明显的影响。本文实验研究了Si与B含量间的相对变化对(Fe_(80)Ni_(20))_(78)Si_(22-x)B_x合金的饱和磁矩、平均原子磁矩与Curie温度的影响关系。利用电子转移模型与分子场近似理论定性的解释了(Fe_(80)Ni_(20))_(78)-Si_(22-x)B_x合金的磁矩(M_s)与Curie温度(T_c)随
When the liquid quenching method is used to prepare the amorphous alloy strip, it is necessary to form an amorphous state by adding 15-30% of B, Si and the like. However, due to the addition of Si and B and other metal elements, the magnetic properties of amorphous alloys are significantly affected. In this paper, we study the relationship between the relative change of Si and B content on the saturation magnetic moment, the mean atomic magnetic moment and the Curie temperature of (Fe 80 Ni 20 (20) Si 22-x B x) alloys . The magnetic moment (M_s) and Curie temperature (T_c) of (Fe_ (80) Ni_ (20)) _ (78) -Si_ (22-x) B_x alloys are qualitatively explained by the electron transfer model and the molecular field approximation theory
