发明名称 MAGNETIC MATERIAL
摘要 <P>PROBLEM TO BE SOLVED: To improve the characteristics of a magnetic material without using a rare earth element which is a rare resource. <P>SOLUTION: On the surface of particles of a magnetic powder, a film of a fluorine compound containing hydrogen, nitrogen, fluorine, and a metal element, where hydrogen is contained more than nitrogen and fluorine is contained more than the metal element, is formed. A magnetic material in which the magnetic characteristics of the magnetic powder are improved without using a rare earth element can be obtained by making an element contained in the film intrude between the lattices of a crystal composing the particles of the magnetic powder. <P>COPYRIGHT: (C)2012,JPO&INPIT
