Description
以下、本発明者等が行った実験例1を説明する。図3は実験例1の内容を示す表である。この実験例1では、先ず図3に示す5種類の組成の溶湯を、水アトマイズ法を用いてそれぞれ粉末化し、それを分級して21〜23μmの平均粒径を備えた非晶質軟磁性金属粉末を得、それを用いて、5種類の試料すなわち比較例1および2と実施例1〜3とを、図2の製造工程と同様の工程を経て作成し、粉末の酸素量、非晶質度、飽和磁化、圧粉磁芯のコアロスをそれぞれ測定し、測定結果を図3の表1に示す。
次に、本発明者等が行った実験例2を説明する。図4は実験例2の内容を示す表である。この実験例2では、先ず図4に示す37種類の組成の溶湯を、ガスアトマイズ法を用いてそれぞれ粉末化し、それを〜25μm、25〜38μm、38〜45μmの3種類の粒径に分級した非晶質軟磁性金属粉末を得、それを用いて、41種類の試料すなわちNo.1乃至No.41について飽和磁化と、さらに上記3種類の粒径毎の非晶質度とを、前述の実験例1と同様の方法でそれぞれ測定した。その測定結果を図4に示す。
