Abstract Gd 3Rh, Gd 3Ir and Gd 3Pd were obtained by the Czochralski method from a levitated melt. Powder diffraction patterns were studied. The crystal structure was determined as Fe 3C-type. The magnetic susceptibility was measured in a wide temperature range (4.2–800 K). For Gd 3Rh an antiferromagnetic transition was observed at 112 K, whereas for Gd 3Ir a ferromagnetic transition was obtained at 155 K. For Gd 3Pd a ferromagnetic transition was observed at 325 K. The enhancement of the effective magnetic moment calculated per gadolinium ion, in relation to the theoretical value, was 0.55 μ B for Gd 3Rh, 0.18 μ B for Gd 3Ir and −0.28 μ B for Gd 3Pd. This effect may be related to spin fluctuations due to hybridization of the almost empty 5d states of gadolinium with the almost full 4d (or 5d) states of the transition metal.
