Abstract
The 205Tl nuclear spin-spin relaxation rate in single crystals of Tl2Ba2CaCu2O8 is studied at different angles θ between the c-axis and the magnetic field. We observe a peak caused by vortex motion at T/Tc≈ 0.2. The peak temperature increases, and height decreases with increasing θ. From the data, we extract information about the hopping distance and frequency.
