Abstract A logarithmical decrease in the resistivity below 10 K has been observed for 200 to 5,000 ppm Gd in Y and Sc. The decrease scales with the Gd concentration. The results are in line with previously published data forLu: Gd and LaAl2: Gd, they are discussed in terms of a ferromagnetic (J〉0) Kondoeffect. The scaling parameterT K , and the extracted effective change interactionJ eff are compared with other experimental results. In addition the negative magnetoresistance (the freezing out of spin-disorder scattering) has been measured up to 50 kG. Possible interference of potential and exchange scattering may have been observed in the magnetoresistance.
