Abstract
From magnetoresistance measurements in PtFe and PdCo alloys we show that disalignment within the ferromagnetic state begins at concentrations well above a critical concentration at which spin glass order sets in. In PtFe the ferromagnetic to spin glass transition is second order.
Résumé
A partir de mesures de magnétorésistance sur des alliages de PtFe et de PdCo, nous montrons qu'un désalignement au sein de l'état ferromagnétique se manifeste à des concentrations bien au-dessus de la concentration critique à laquelle l'ordre verre de spin s'installe. Pour le PtFe la transition ferromagnétique-verre de spin est de deuxième ordre.
