METHOD OF COMBINING MAGNETIC ULTRA-FINE PARTICLES OF RARE-EARTH METAL |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a method of combining magnetic ultrafine particles for creating a new material for the purpose of attaining high density in magnetic recording. <P>SOLUTION: Fatty acid rare-earth metal salt or fatty acid transition metal salt is heated by microwaves in a glycerine solvent. The magnetic ultra-fine particles are SmCo<SB>5</SB>, for example. <P>COPYRIGHT: (C)2007,JPO&INPIT |
