Investigation of Superconductivity in Ce-Doped (La,Pr)OBiS(2) Single Crystals

Single crystals of Ce-doped (La,Pr)OBiS(2) superconductors, the multinary rare-earth elements substituted ROBiS(2), were successfully grown. The grown crystals typically had a size of 1–2 mm and a plate-like shape with a well-developed c-plane. The c-axis lattice constants of the obtained (La,Ce,Pr)...

description Single crystals of Ce-doped (La,Pr)OBiS(2) superconductors, the multinary rare-earth elements substituted ROBiS(2), were successfully grown. The grown crystals typically had a size of 1–2 mm and a plate-like shape with a well-developed c-plane. The c-axis lattice constants of the obtained (La,Ce,Pr)OBiS(2) single crystals were approximately 13.6–13.7 Å, and the superconducting transition temperature was 1.23–2.18 K. Valence fluctuations of Ce and Pr were detected through X-ray absorption spectroscopy analysis. In contrast to (Ce,Pr)OBiS(2) and (La,Ce)OBiS(2), the superconducting transition temperature of (La,Ce,Pr)OBiS(2) increased with the increasing concentrations of the tetravalent state at the R-site.
