发明名称 Nanoscale amorphous magnetic metals
摘要 Sonochemistry permits extremely rapid cooling to form nanoscale amorphous metal particles. If magnetic, these particles are valuable for magnetic recording media, manufacture of permanent magnets, and other uses. The nanoscale particles agglomerate, however, which limits their utility for these magnetic applications. To keep the particles isolated, we extract the particles from the n-alkane reaction solvent in a polar solvent and cast the extracted particles with a polymer, such as polyvinylpyrrolidone.
