Abstract We have measured the resistive upper critical field of overdoped single crystals of Tl2Ba2CuO6 from the zero-field transition temperatureT c (approximately 20 K) to temperatures as low as 12 mK, corresponding to less than 0.001T c. In sharp contrast to the predictions of standard theories of superconductivity, the critical field is found to rise steeply with positive curvature as the temperature is reduced, and no sign of saturation is observed down to the lowest temperatures reached.
