Abstract

Abstract The ordered Laves phases RE Ni 4 Cd ( RE = Sc, Y, Ce, Pr, Nd, Sm, Gd–Lu) were obtained by melting of the elements in sealed tantalum ampoules in a muffle furnace followed by slow cooling of the samples down to 773 K. The compounds were characterized by powder X-ray diffraction. The structures of YNi 4 Cd, GdNi 4 Cd, and LuNi 4 Cd were refined on the basis of X-ray single crystal data. Magnetic susceptibility measurements show intermediate valence for CeNi 4 Cd and Curie–Weiss behavior for GdNi 4 Cd with an experimental magnetic moment of 7.89(1) μ B /Gd atom and θ P = 1.6(5) K. GdNi 4 Cd orders antiferromagnetically at 4.5(5) K.
