| 简介 |
A thick magnet film contains a rare earth magnet phase represented by formula R-M-X, where R contains at least one of Nd and Sm, M contains at least one of Fe and Co, and X contains at least one of N and B. The thick magnet film has a density of equal to or more than 80% but less than 95% of the theoretical density when R contains Nd as a main component and has the density of equal to or more than 80% but less than 97% of the theoretical density when R contains Sm as a main component. The magnet can achieve an increase in thickness when formed into a film, an increase in density and an improvement in magnetic properties such as residual magnetic flux density. |
