Abstract

The investigations of the magnetic and electrical properties as well as the 57Fe Moessbauer effect are presented for Ce1-xScxFe4Al8 solid solution with 0<x<1 in the temperature range 4-300 K. Magnetic susceptibility follows a Curie-Weiss law above 200 K. The effective magnetic moment decreases with the Sc content. At temperatures lower than 130 K all compounds studied are antiferromagnets. The Neel temperature, TN is not affected by substitution of Sc for Ce. TN has no reflection in any anomaly in ρ(T). The Moessbauer spectra at temperatures lower than TN exhibit one Zeeman sextet related to the Fe nucleus at the 8(f) position. The hyperfine parameters Hhf, IS, QS have been estimated as a function of Sc concentration. The increasing of Sc c...
