Abstract

PURPOSE: To improve characteristics such as maximum energy product, residual magnetization and coercive force as a magnet by specifying parameters such as Co, Fe and Cu in the permanent magnet containing Ce as a rare earth element.
CONSTITUTION: In the permanent magnet alloy containing rare earth metals shown by Ce1-uSmu(Co1-x-yFexCuy)z, the respective parameters are specified at 0≤u≤ 0.3, 0.16≤x≤0.18, 0.12≤y≤0.14, 5.7≤z≤6.0. This alloy has the compositin of, e.g., Ce0.9Sm0.1(Co0.71Fe0.16Cu0.13)5.85. Grinding the ingot of this composition followed by compression molding and sintering in a magnetic field and cooling yields the permanent magnet product of superior maximum energy product, resudual magnetization and coercive force. If it is aged after sintering, it will have higher coercive force.
