 Abstract: We report measurements on the resistivity, susceptibility and ESR vs. temperature of monopnictides MZ (with M=Sc, Y, La and Z=As, Sb, Bi) which contain small amounts of Ce- or Yb-ions as doping material. Metallic conductivities are found in all of these systems. With increasing covalent character of the MZ host we observed: an increasing conductivity, a decreasing crystal-field splitting of the Ce3+- or Yb3+-ionic state and for both 4f-ions an increase of the negative 4f-conduction electron exchange constant.
