发明名称 RARE EARTH MAGNET AND ITS MANUFACTURING METHOD
摘要 <P>PROBLEM TO BE SOLVED: To provide a rare earth magnet having a small temperature dependency of a magnetic property and a method of manufacturing such a rare earth magnet. <P>SOLUTION: The method of manufacturing the rare earth magnet with a composition including a ferromagnetism phase and a grain boundary phase, in which the ferromagnetism phase includes a hard magnetism phase comprising a R<SB>2</SB>Fe<SB>14</SB>B-type compound phase and a soft magnetism phase, comprises the steps of: preparing an alloy melt having a predetermined composition in which an element configuring the grain boundary phase includes a primary additional element where a mixed enthalpy with Fe is zero or more; and heating the solidified alloy to a predetermined temperature by temperature rising over 100K/sec. <P>COPYRIGHT: (C)2005,JPO&NCIPI
