Title:
強磁性合金および強磁性合金の製造方法
Document Type and Number:
Japanese Patent JP6483839
Kind Code:
B2
Abstract:
A Y—Fe ferromagnetic alloy formed by a rapid quenching process, in which a Fe element is not substituted partially or entirely by a structure stabilization element, has high magnetization, but still has a magnetic anisotropy that is too small for practical use. The present invention teaches that Gd is substituted partially for a binary system Y—Fe or a ternary system Y—Fe—Co as a main composition, thereby a magnetic anisotropic magnetic field can be increased, and Gd is substituted partially for a quaternary system Y—Sm—Fe—Co, thereby a magnetic anisotropic magnetic field does not vary or is reduced.
