چکیده انگلیسی
In this study, cubic single crystals of the magnetic superconductor Ru1âxSr2âyGd1+yCu2+xO8âδ (RuGd-1212) with typical dimensions of 100-150 µm in length were grown by the partial melting technique. Multiple 00l reflections were first observed by XRD measurements of the bulk RuGd-1212 single crystals. The resistivity of the obtained crystals was roughly estimated to be â¼24-80 mΩ cm and no superconducting transition was observed down to 4.2â¯K. From the XRD measurements and refinement of the crystal structure, it was apparent that the Ru and Sr sites of the single-crystal RuGd-1212 were partially substituted by Cu and Gd, respectively. Oxygen defects were found to be minor (δ â 0.1). The lattice parameters a and c of the single crystals were found to be larger and smaller, respectively, than those of a polycrystalline sample.
