PROBLEM TO BE SOLVED: To improve the characteristics of a magnetic material without using a heavy rare-earth element as a scarce resource.SOLUTION: A magnetic material is manufactured which ensures magnetic characteristics, such as a coercive force and a residual flux density, by introducing fluorine into a magnetic powder and controlling the crystal orientation in crystal grains. As a result, solve the problem of heavy rare-earth element resource is solved, and the magnetic material is applicable to the magnetic circuits that require a high energy product, including various rotating machines and voice coil motors of hard discs. |
