摘要
研究了类金属 Si 和 B对(Fe_(80)Ni_(20))_(78)Si_2B_(22-x) 系非晶磁性合金居里温度T_c 和晶化温度T_x 的影啊。实验发现,随Si 含量的增加(或随 B 含量的减少),T_c 降低,T_x 增加。T_c 的这一变化规律可用本文提出的有效 Fe 原子数的变化来解释;T_x 的变化规律可用类金属价电子密度 e/a 的变化来解释。
Experimental results show that as Si content is increasing or B contentdecreasing, then Curie temperature T_c lowers and crystallization temperatureT_x raises. The variation of T_c can be elucidated on the basis of the number ofeffective Fe atoms, which is presented in this paper; while the variation ofT_x can be elucidated with metalloid's valence electron density e/a.
