摘　　要：通过比较Finemet金属非晶薄带,在较低退火温度(450℃、500℃、530℃)下矫顽力Hc、剩磁Br以及损耗Ps的差异,得出关于其软磁性能优劣的结论,力图阐明退火温度等对Finemet金属晶化过程及软磁性能的影响。利用线性拟合的方法,得出了不同频率下关系式Ps=aT+b当中的常数a、b,进一步说明了Finemet金属薄带在高频时的优异软磁性能。The soft magnetic properties including He, Br and P, of the captioned Finemet alloy annealed at different temperatures are compared in order to expound the effect of the annealing temperatures on the crystallization process and especially soft magnetic properties of the Finemet film. The value of a and b in Ps = aT ＋ b were presented through linear integration. It is found that at high frequencies, the soft magnetic properties of the Finemet are excellent.
