| titleOfInvention | Rare earth bonded magnet including amino-acid compound as lubricant |
| abstract | In a rare earth bonded magnet comprising a mixture of rare earth magnetic powder, thermosetting resin, and lubricant, the lubricant is constituted by amino-acid compound, specifically either N-lauroyl-L-lysine or N-lauroyl-asparaginic acid. The content of the amino-acid compound as lubricant in the mixture is set to range between 0.01 wt % and 1.0 wt % of the magnetic powder. Since the amino-acid compound has a high decomposition point, the resultant magnet after heat-curing treatment has a sufficient mechanical strength. Also, the amino-acid compound is nonhygroscopic, and therefore oxidation resistance and humidity resistance are good enough. Further, since the amino-acid compound produces a small amount of outgas, the resultant magnet can be suitably and reliably used in a hard disk drive which has stringent requirements, especially on outgas. |
