    • In the production by the single-roll technique of a thin amorphous strip as the matrix for the manufacture of a thin Co-based amorphous alloy strip or a thin Fe-based microcrystalline alloy strip, the conditions for the production are controlled to those specified by the invention. The production conditions thus controlled concern the atmosphere and the pressure to be used for ejecting a molten metal onto a rotating cooling member, the shape of a nozzle, the distance between the nozzle and the rotary cooling member, the material for the rotary cooling member and peripheral speed of the rotary cooling member, etc. The individual numerical values of these conditions are severally important. The thin strip which has an extremely small thickness and few pinholes thus is obtained. In the thin Co-based amorphous alloy strip, the extreme decrease of thickness to below 4.8 .mu.m notably enhances the soft magnetic properties such as permeability and core loss in the high frequency range. In the thin Fe-based microcrystalline alloy strip, the extreme decrease of thickness not more than 10 .mu.m permits improvement of resistance to embrittlement in addition to the improvement in the soft magnetic properties.
    • 在通过单辊技术制造薄的非晶带作为用于制造薄的Co基非晶态合金带或薄的Fe基微晶合金带的基体的生产中,将生产条件控制为由 本发明。 由此控制的生产条件涉及气氛和用于将熔融金属喷射到旋转冷却构件上的压力,喷嘴的形状,喷嘴和旋转冷却构件之间的距离,旋转冷却构件的材料和 旋转冷却构件的圆周速度等。这些条件的各个数值是重要的。 获得了具有非常小的厚度和很少的针孔的细条。 在薄的Co基非晶态合金带中,厚度的极端降低至4.8μm以下,显着提高了高频范围内的磁导率和磁芯损耗等软磁特性。 在薄的Fe基微晶合金带中,除了软磁性能的提高之外,厚度的极大降低不超过10μm,允许改善耐脆性。
