Abstract

Tl2Ba2CuO6+delta. There crystals with different levels of oxygen overdoping were investigated in magnetic fields up to 10 T. In all cases, the magnetization above the irreversibility line was found to depart from the behavior M similar to In(eta H-c2\H) of a simple London-like vortex liquid. In particular, for a strongly overdoped (T-c =15 K) crystal, the remnant superconducting order above the irreversibility line is characterized by a linear diamagnetic response (M similar to H) that persists well above T-c and also up to the highest field employed.
