| 简介 |
To provide a magnet which can achieve all of the increase in thickness when formed into a film, the increase in density and the improvement in magnetic properties (in particular, residual magnetic flux density).
The problem can be solved by a thick magnet film characterized by containing a rare earth magnet phase represented by formula (1) ; R-M-X (in the formula, 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) , in which it has the density of equal to or more than 80% but less than 95% of the theoretical density when R has 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 has Sm as a main component. |
