摘要
本文报道不同温度退火后,双相结构纳米晶Fe_(73)Cu_1Nb_(1.5)MO_2Si_(12.5)B_(10)合金的起始磁化率的温度关系。实验结果表明,退火温度对这种关系有明显影响。用Hernando等人提出的双相结构唯象理论作了解释,认为这种关系是由纳米α-Fc(Si)晶粒通过粒间非晶界而层传递交换耦合作用决定的。
In the present paper, the temperature dependence of the Initial suscpetlblll-ty of the two-phase nanocrystalllne Fe73Cu1Nb1.5MoaSi12.5B10 alloy annealed at various temperature is reported. The experimental results have shown that this dependence is strongly Influenced by th temperature of nanocrystalllzatlon annealing. The results have interpreted by using the two-phase phenomenological theory proposed by Hernando et al. It can be considered that this dependence Is determined by the exchange couplings among a -Fe(Sl) grains transmitted through the Intergranular amorphous layers.
