| Abstract: | A new closed-atmosphere method using a gold crucible has been developed to grow single crystals of the Tl-based cuprate superconductors by a self-flux growth method. This new method can provide us mm-sized single crystals of Tl2Ba2CuOx. It should be noted that the value in the resistivity ratio R(300K)/R(Tc) (RRR) of one of the as-grown crystals is 18.3. This high RRR value indicates that the newly developed method is useful to obtain extremely high-quality single crystals of Tl2Ba2CuOx. |
