Nous présentons une contribution expérimentale à l’étude des propriétés structurales et magnétiques de ferrites de gallium substituées par des terres rares. Ce travail s’inscrit dans la thématique plus générale des multiferroïques magnétoélectriques dont fait partie le composé Ga2-xFexO3 qui est ferrimagnétique et présente une polarisation spontanée à température ambiante. On s’intéresse à l’influence de la substitution d’atomes de gallium ou de fer par des éléments de terres rares (Sc, Yb, Er, Sm) sur les paramètres structuraux de Ga2-xFexO3 avec 0,9 x 1,2 et à l’effet de la substitution par Sc et Yb sur la température de transition magnétique et l’aimantation à saturation. On présente une étude expérimentale du magnétisme du composé Ga0...
