Abstract
We show in-plane and out-of-plane angular dependent torque data on underdoped Bi2Sr1.4La0.6CuO6+δ single crystals. We find that the superconducting signal persists well into the normal state, at least up to twice the zero-field superconducting transition temperature Tc0. The superconductivity is highly anisotropic below Tc0, while its anisotropy decreases significantly just above Tc0. In this latter T regime the Cooper pairs lose their long-range phase coherence.
