Résumé
Les mesures calorimétriques à basses températures sur trois échantillon de Gdx Er1-xRh4B4 avec x = 0,09 ; 0,28 et 0,65 indiquent l'existence d'une transformation de structure au voisinage de la température 11 K. Les processus d'ordre magnétique se présentant à des températures plus basses ont été identifiés par des données de capacité calorifique comme étant de nature ferromagnétique
Abstract
Low temperature calorimetric measurements on three Gdx Er 1-x Rh4 B4 samples with x = 0,09 ; 0,28 and 0,65 indicate a structural transformation near l l K. The magnetic ordering occuring at lower temperatures have been identified by the heat capacity data as ferromagnetic in nature.
