Abstract

The RuSr2GdCu2O8 - δ (Ru-1212) superconductors have been prepared through the sol-gel route. We found that 1030 °C is the optimum annealing temperature for the formation of the Ru-1212 superconductors synthesized by the sol-gel route. X-ray powder diffraction analysis indicates that nearly all the peaks from the samples can be indexed to a single phase of Ru-1212, tetragonal symmetry with lattice parameters a = b = 3.382 Å, c = 11.478 Å and space group I4/mmm. The RuSr2GdCu2O8 - δ superconductors prepared by the sol-gel method exhibit onset transition temperature Tc-onset near 55 K and zero resistance temperature Tc-zero at 45 K.
