Valence admixture in the Eu/sub /ital x//Rh/sub 1/minus//ital x// amorphous alloys

Magnetic, M/umlt o/ssbauer, and /ital L//sub III/-edge measurements are reported on the Eu/sub /ital x//Rh/sub 1/minus//ital x// amorphous alloys. The experimental results clearly indicate that an inhomogeneous valence admixture occurs in the disordered phase. The fluctuating valence encountered in the crystalline EuRh/sub 2/ is destroyed by the structural disorder. The average valence is discussed in terms of local environment.
