从三种钴基金属玻璃的磁场退火感生磁各向异性的弛豫曲线的分析,得出弛豫时间τ的对数正态分布宽度β与温度倒数1/T呈线性关系,分析结果说明,在此弛豫过程中,lnτ0和激活能E都服从正态分布,前者的分布宽度β0≈3,后者的分布宽度βe≈0.34eV。From the analysing of the relaxation curves of magnetic annealing induced anisotropy of three cobalt based metal glasses, a linear relationship between the width of lognormal distribution of relaxation times (β) and the reciprocal temperature (1/T) has been established. This result implies that, in the process of relaxation, both Inτ0 and activation energy E obey the Gaussian distribution. The width of distribution for Inτ0 and E have been estimated.
