摘要：

Susceptibility, resistivity and X-ray diffraction measurements have been performed on single crystals of Bi2Sr2CaCu2O8+delta. Very sharp (0.5 K width) superconducting transition temperatures as low as 55 K have been reached in the overdoped part of the phase diagram. Anneals in low oxygen pressures have allowed us to access the entire underdoped region of the phase diagram. The samples have been reversibly changed from a high-temperature superconductor to an insulator.
