Abstract

Magnetic-field gradients in the mixed state of a type-II superconductor are studied using Tl205 nuclear magnetic resonance (NMR) on Tl2Ba2Ca2Cu3O10+δ. An anomalous peak was observed in the temperature dependence of the transverse relaxation rate at T/Tc0.25. We attribute this behavior to magnetic-field flucutations from vortex dynamics. We interpret this behavior as a crossover of the principal time scale for vortex dynamics with that of the NMR experiment, approximately 100 μs. The temperature dependence of this time scale is discussed.
