Hyperfine fields and magnetic coupling in Gd metal

New hyperfine field measurements on transition metal impurities in Gd are reported. The data cannot be explained on a simple RKKY model, but are consistent with a mechanism in which magnetic coupling is through the d electrons. Nous presentons des nouveaux résultats sur les champ hyperfins d'im...

Description
Summary:New hyperfine field measurements on transition metal impurities in Gd are reported. The data cannot be explained on a simple RKKY model, but are consistent with a mechanism in which magnetic coupling is through the d electrons. Nous presentons des nouveaux résultats sur les champ hyperfins d'impuretes 3d et 5d dans une matrice de Gd ferromagnetique. Le modèle simple d'interactions RKKY n'explique pas les données expérimentelles; par contraste, un modèle de couplage par les electrons d donne une explication consistente.
