Abstract: We report on the electrical resistivity and magnetic susceptibility of La or Gd doped RCrSb 3 ͑R = La, Pr, Sm, and Gd͒. Single crystals were grown by increasing the nominal dopant by 25%. In general, two magnetic ordering transitions are found, T c1 is attributed to ferromagnetic ordering of the itinerant Cr sublattice, and, at lower temperatures, T c2 is attributed to ordering of the localized rare-earth sublattice. Alloying on the rare-earth site varies the de Gennes factor, DG= ͑g −1͒ 2 J͑J +1͒, and dT c1 …
