THICK RARE EARTH MAGNET FILM AND LOW-TEMPERATURE SOLIDIFYING AND MOLDING METHOD

摘要

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.

1. A thick magnet film comprising:
a rare earth magnet phase represented by a formula R-M-X, wherein R includes at least one of Nd and Sm, M includes at least one of Fe and Co, and X includes at least one of N and B, the thick magnet film having a density of equal to or more than 80% but less than 95% of a theoretical density when the R has Nd as a main component, and having a density of equal to or more than 80% but less than 97% of the theoretical density when the R has Sm as the main component, and wherein the thick magnet film does not have a binder material.
