Abstract
Tl2Ba2CuO6+delta. There crystals with different levels of oxygen overd oping were investigated in magnetic fields up to 10 T. In all cases, t he magnetization above the irreversibility line was found to depart fr om the behavior M similar to In(eta H-c2\H) of a simple London-like vo rtex liquid. In particular, for a strongly overdoped (T-c =15 K) cryst al, the remnant superconducting order above the irreversibility line i s characterized by a linear diamagnetic response (M similar to H) that persists well above T-c and also up to the highest field employed.
