Title:
THICK RARE EARTH MAGNET FILM, AND LOW-TEMPERATURE SOLIDIFICATION MOLDING METHOD
Document Type and Number:
Japanese Patent JP2013120798
Kind Code:
A
Abstract:
To provide a magnet simultaneously satisfying increased film thickness, increased density, and improved magnetic characteristics (specifically, residual magnetic flux density).
A thick magnet film contains a rare earth magnet phase represented by formula (1): R-M-X (in the formula, 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.), and has a density of 80% or more and less than 95% of the theoretical density when the R contains Nd as the main ingredient, while having a density of 80% or more and less than 97% of the theoretical density when the R contains Sm as the main ingredient.
