In order to investigate the magnetic properties of the solid solution CePt 1– x Pd x Al the individual compounds were synthesized from the elements using an arc furnace. From x = 0–0.8 the solid solution crystallizes in the orthorhombic TiNiSi‐type structure ( Pnma , no. 62; a = 721–722, b = 448–453 and c = 778–779 pm) and for x = 0.9 both the TiNiSi‐ as well as the hexagonal ZrNiAl‐type structures were observed. The solid solution exhibits an interesting magnetic behavior as for small values of x ferromagnetic ordering can be found. At higher palladium content this changes towards an antiferromagnetic ordering. Furthermore the solid solution exhibits a spin‐reorientation ( meta ‐magnetic step) for x = 0.2–0.7.
