Reduction of Anisotropy in the Rapidly Quenched Iron-Silicon Ribbon.

使用含约6.5wt.%的高硅铁单晶，硅，饱和磁化强度的淬火温度依赖性，磁晶各向异性常数进行了测量。在4.9-6.0wt.%的范围内，测量了晶体的饱和磁化强度和各向异性常数与从1,100 ℃缓慢冷却的晶体相比，从1,100 ℃淬火到油中的硅分别显示出高达12%和80%的降低。淬火晶体的饱和磁化强度和各向异性常数的减少和饱和磁致伸缩常数的增加与从X射线测量计算的序参数中的分泌物相关。生长了十多个不同成分的含钛高硅铁合金单晶。对磁器件的磁滞特性和各向异性进行了测量，计算具有饱和和磁滞特性的磁器件的磁场分布需要蔡氏模型的几个参数。

Using high silicon-iron single crystals containing around 6.5wt.% silicon, the quenching temperature dependence of the saturation magnetization, the magnetocrystalline anisotropy constant were measured. The saturation magnetization and the anisotropy constant of rhe crystals with 4.9-6.0wt.% silicon quenched into oil from 1,100 C showed decreases of up to 12 and 80%, respectively, compared to crystals cooled slowly from 1,100 C. The decreases in the saturation magnetizations and the anisotropy constants and the increases in the saturation magnetostriction constants for the quenched crystals were correlated with secreases in an order parameter calculated from x-ray measurements. More than ten single crystals of high silicon-iron alloys containing Ti with various compositions were grown. The hysteretic properties as well as anisotropy measurements were carried out.A couple of parameters of a Chua type model are necessary to calculate the field distribution of any kinds of magnetic devices, which exhibit the saturation and hysteresis.
