    Abstract

    Single crystals of Bi2,2Sr1.8Ca2Cu 3O10+δ (Bi2223) with x = 0.2 were grown by a traveling solvent floating zone method in order to investigate the superconducting properties of highly underdoped Bi2223. Grown crystals were characterized by X-ray diffraction, DC susceptibility and resistivity measurements, confirming Bi2223 to be the main phase. The crystals were annealed under various oxygen partial pressures to adjust their carrier densities from optimally doped to highly underdoped. The fluctuation diamagnetic component above the superconducting transition temperature Tc extracted from the anisotropic normal state susceptibilities χab (T) (H ⊥ c) and χc(T) (H ∥ c) was found to increase with underdoping, suggesting a decrease in the superconducting dimensionality and/or increase in the fluctuating vortex liquid region.
