Beschreibungen/Notizen

• The intersublattice R-T exchange coupling parameter (ART) in amorphous Gd1 − xCox has been evaluated from the values of the Curie temperatures or of the compensation temperatures. As the Co composition increases, AGdCo is found to decrease. Such a variation is similar to that observed for crystalline alloys. However, AGdCo is smaller in the amorphous than in the crystalline state. The results are discussed in terms of the influence of amorphicity on the 3d–5d hybridization.
