Abstract
Evolution of the structural, magnetic, transport and magneto-transport properties of the Ce1-xLaxFeGe3 series is studied by powder x-ray dif fraction, Fe-57 Mossbauer spectroscopy, magnetization and resistivity in zero and applied magnetic field. Changes from concentrated Kondo sy stem-like (x less than or equal to 0.3) to single Kondo ion-like (x gr eater than or equal to 0.65) behaviour are observed. Magneto-resistivi ty behaviour in both regimes is discussed within the existing theoreti cal views which include non-negligible 'normal' metal contributions.
