High-Quality Large-Sized Single Crystals of Pb-Doped Bi₂Sr₂CuO_6+δ High-T_c Superconductors Grown with Traveling Solvent Floating Zone Method

High quality Pb-doped Bi₂Sr₂CuO_6+δ (Pb-Bi2201) single crystals are grown by the traveling solvent floating zone technique, with dimensions as large as ~50 mm×~5.0 mm×~2 mm. The Pb-Bi2201 single crystals with different doping levels are obtained by the annealing process which covers a wide doping range of the overdoped region. We describe in detail the growth and annealing procedures and the characterization and physical property measurements of the Pb-Bi2201 crystals. The availability of these crystals provides a good opportunity to experimentally investigate high-Tc cuprate superconductors, particularly in the overdoped region.
