We report the preparation procedure of RuSr2 (Gd2-x Cex)Cu2Oz (Ru-1222) cuprate superconductors from x = 0.5 to 0.7 using the solid state reaction method. All compositions showed an almost single Ru-1222 phase with tetragonal symmetry in the 14/mmm space group and semiconducting or semi-metallic nor...
