A method of manufacturing ferrite crystals such as single crystal bodies and polycrystal bodies with garnet structure is disclosed, which includes the steps of effecting a composition controlling of raw powders, forming raw powders, sintering formed bodies and effecting hot isostatic press treatment of sintered bodies. Also, a method of producing ferrite powders preferably used for the ferrite crystal manufacturing method mentioned above. The thus obtained ferrite crystal bodies with garnet structure show good magnetooptical properties such as light transmissivity, Faraday rotation angle and Verdet constant, and are preferably used for magnetooptical elements such as optical isolators and optical magnetic field sensors etc.
Méthode pour fabriquer des cristaux de ferrite, notamment des corps monocristallins et des corps polycristallins à structure de grenat, qui comprend les étapes suivantes: faire un contrôle de composition de poudres brutes, former des poudres brutes, fritter les corps formés et faire le traitement de compression isostatique à chaud des corps frittés. Également une méthode pour produire des poudres de ferrite utilisées de préférence dans la méthode de fabrication mentionnée ci-dessus. Les corps cristallins à structure de grenat ainsi obtenus démontrent de bonnes qualités magnéto-optiques telles que la capacité de transmission de la lumière, l'angle de rotation Faraday et la constante de Verdet, et sont utilisés de préférence pour la fabrication d'éléments magnéto-optiques tels que des isolateurs optiques, des capteurs de champs magnétiques optiques, etc.
