From resistivity and magnetoresistance data on AuFe we conclude that above the concentration where ferromagnetic order appears, in the low temperature state ferromagnetic and spin glass like ordering coexist. As the temperature is increased a transition to normal ferromagnetic order is indicated by a well defined minimum in the susceptibility above technical saturation.A partir de mesures de résistivité et de magnétorésistance sur des alliages AuFe, nous trouvons qu'audela de la concentration où l'ordre ferromagnétique se manifeste, les ordres verre de spin et ferromagnétique coexistent à basses températures. Quand on augmente la température, on observe un minimum dans la susceptibilité au-dessus de la saturation technique. Ceci peut indiqu...
