纳米晶（Fe_（1-x）Co_x）_（73.5）Cu_1 Nb_3Si_（13）的结构和软磁响应对5 B 9（x= 0，0.25，0.5，0.75）合金进行了研究。通过XRD图谱估算晶化体积分数Vcr和晶间非晶层厚度Λ，分析了热处理和Co含量对晶化的影响。通过磁导率从室温到780 ℃的温度变化，分析了高温软磁响应。C.结果表明，当x≤ 0.5时，随着Co含量的增加，样品的高温软磁性能得到改善，这是由于Co含量增加增强了晶体间的磁耦合，但富Co样品的μi值有所下降。所观察到的μi行为作为Co含量的函数被解释为交换耦合程度的变化
Structural and soft magnetic response of nanocrystalline (Fe1-xCox) 73.5 Cu1Nb3Si13. 5B9 (x= 0, 0.25, 0.5, 0.75) alloys were investigated. Influences of heat treatment and Co content on the crystallization were analyzed through estimation of the crystalline volume fraction Vcr and thickness of the intergranular amorphous layer Λ from XRD patterns. High-temperature soft magnetic response was analyzed by the temperature evolution of the magnetic permeability from room temperature to 780 deg. C. It was found that the high-temperature soft magnetic behavior is improved with increasing Co content for x≤ 0.5, which is ascribed to reinforcing magnetic coupling between the crystals, however, a decrease of μi was observed for the Co richest sample. The observed μi behavior as a function of Co content is interpreted in terms of variations in the degree of exchange coupling
