Abstract
The present invention relates to a Sm—Co based magnet alloy useful as a raw material for producing magnets having high magnetic properties, such as sintered or bonded magnets, methods for producing such an alloy, and sintered or bonded magnets having excellent corrosion resistance and high magnetic properties, such as high coercivity and good squareness. The magnetic alloy is composed of an alloy represented by the formula RM with 32.5 to 35.5 wt % R such as Sm and the balance of M such as Co, wherein ratio (B/A) of the X-ray diffraction intensity (B) corresponding to the (119) plane of RMphase to the X-ray diffraction intensity (A) corresponding to the (111) plane of RMphase is not higher than 0.1.
