Polycrystalline samples of Ru 1-x Sb x Sr 2 GdCuO 8 doped with Sb , in which magnetic order and superconductivity coexist with T magnetic ≫T c , were prepared by a solid state reaction technique. Lattice parameters, electrical resistivity, Hall and thermopower coefficients measurements on the same sintered ceramic samples are presented. Both Hall effect and thermopower show anomalous decreases below T magnetic which might be explained with a simple two-band model in the RuO 2 layer at T magnetic . It was also observed that the Sb doping reduce the conductivity of the system and the transition temperature decreases with increasing Sb content. This may be due to a distortion of RuO 6 octahedra which is responsible for the increase of hole localization.
