Document Type and Number:
Japanese Patent JP2018061012
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a novel permanent magnet arranged without performing a nitriding treatment nor using a rare earth element involving a future resource risk and a rising-price risk, and a method for manufacturing the permanent magnet.SOLUTION: A permanent magnet comprises: Fe in a range between 37 and 46 atom%; Mn in a range between 30 and 40 atom%; and Ga in a range between 22 and 30 atom%. The permanent magnet has a main phase of a tetragonal structure, and satisfies the following expression (1): Fe>Mn (1). (In the expression (1), Fe shows an Fe content represented by atom%, and Mn shows a Mn content represented by atom%.)SELECTED DRAWING: Figure 2
