Abstract

L'invention a pour objet un élément magnéto-optique sans plomb qui est caractérisé par une nanocouche magnétique fine composée d'une nanofeuille de titane avec un substituant magnétique simultané, obtenue par séparation de couches de dioxyde de titane avec un minimum de deux substituants magnétiques simultanés différents au niveau du réseau moléculaire du titane. Cet élément magnéto-optique sans plomb exerce d'importants effets électro-optiques sur une large gamme de longueurs d'onde partant des ultraviolets et atteignant presque les infrarouges.
