Title
(EN) LIGHT RARE EARTH MAGNET AND MAGNETIC DEVICE
(FR) AIMANT AUX TERRES RARES LÉGER ET DISPOSITIF MAGNÉTIQUE
(JA) 軽希土類磁石及び磁気デバイス
Abstract
(EN)
Disclosed is a magnet which has higher magnetic characteristics than conventional magnets. Specifically disclosed is a light rare earth magnet that is configured of (a) a light rare earth element to which a light element is added, and (b) iron or cobalt. In this connection, an element, the p orbital level of which is deeper than the d orbital level of iron or cobalt by 1 eV or more, is used as the light element.
(FR)
L'invention décrit un aimant qui a des caractéristiques magnétiques supérieures à celle des aimants classiques. L'invention porte plus précisément sur un aimant aux terres rares léger qui est formé de (a) un élément des terres rares léger auquel un élément léger est ajouté et (b) de fer ou de cobalt. Dans ce cas, on utilise comme élément léger un élément dont le niveau orbital p est plus bas que le niveau orbital d du fer ou du cobalt de 1 eV ou plus.
(JA)
 従来よりも磁気特性の高い磁石を実現する。(a)軽元素の添加物を有する軽希土類元素と(b)鉄又はコバルトとで構成された軽希土類磁石を提供する。ここで、軽元素として、そのp軌道準位が鉄又はコバルトのd軌道準位より1eV以上深くなるものを使用する。
