Title:
A manufacturing method of a magnetic material
Document Type and Number:
Japanese Patent JP6033768
Kind Code:
B2
Abstract:
In a magnetic material, a magnet powder and an amorphous metal are used as ingredients. The magnet powder is neodymium-iron-boron magnet powder. The amorphous metal contains a rare-earth element, iron, and boron. The amorphous metal contains the rare-earth element in the range of 22 to 44 atomic %, and the boron in the range of 6 to 28 atomic %. The magnetic material is obtained by mixing the magnet powder and the amorphous metal, and heating the mixture to a temperature or more, the temperature being lower by 30° C. than the crystallization temperature (Tx) of the amorphous metal, or when the amorphous metal is a metallic glass, heating the mixture to a temperature of the glass transition temperature (Tg) thereof or more.
