THICK RARE EARTH MAGNET FILM, AND LOW-TEMPERATURE SOLIDIFICATION MOLDING METHOD

摘要

[Problem] 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 (particularly a residual magnetic flux density). [Solution] The problem can be achieved by a thick magnet film characterized by containing a rare earth magnet phase represented by formula (1): R-M-X (wherein R comprises Nd and/or Sm; M comprises Fe and/or Co; and X comprises N and/or B), wherein the density of the film is up to 80% and less than 95% of the theoretical density when R is mainly composed of Nd, and the density of the film is up to 80% and less than 97% of the theoretical density when R is mainly composed of Sm.
