Title (EN) COMPOSITE MAGNETIC MATERIAL FOR MAGNET AND METHOD FOR MANUFACTURING SUCH MATERIAL
(FR) MATÉRIAU MAGNÉTIQUE COMPOSITE POUR AIMANT ET PROCÉDÉ DE FABRICATION DE CE MATÉRIAU
(JA) 磁石用複合磁性材料、及びその製造方法
Abstract: front page image
(EN)Provided is a composite magnetic material having high magnetic characteristics and high electrical resistivity to be used for a magnet, especially a composite magnetic material to be suitably used for a rotary motor magnet or the like which functions in a high frequency region. The composite magnetic material for the magnet is provided by covering the surface of a rare earth-iron-nitrogen magnetic material with a ferrite magnetic material.
(FR)L'invention concerne un matériau magnétique composite qui présente de bonnes caractéristiques magnétiques et une forte résistivité électrique et destiné à être utilisé pour un aimant, en particulier un matériau magnétique composite qui convient pour être utilisé pour un aimant de moteur rotatif ou similaires qui fonctionnent dans une plage de hautes fréquences. Le matériau magnétique composite pour aimant est obtenu en recouvrant d'un matériau magnétique de ferrite la surface d'un matériau magnétique à terre rare, fer et azote.
(JA) 磁気特性が高く、電気抵抗率の高い磁石用複合磁性材料、特に高周波領域で機能する回転モータ用磁石などにも好適に利用される磁石用複合磁性材料を提供する。該磁石用複合磁性材料は、希土類-鉄-窒素系磁性材料の表面にフェライト系磁性材料が被覆されてなる。
