摘要：

Results of our nuclear magnetic resonance measurements on two superconducting materials, namely, TlBa1.8La0.2CuO5-y and TlBa1.5La0.5CuO5-y (T(c) = 45 K and 32 K respectively) are reported. The most significant finding of the present work is that the nuclear relaxation rate deviates from Korringa behaviour at a temperature much higher than the superconducting transition temperature T(c). An increase in the linewidth is observed below T(c) which is due to the formation of the vortex lattice.
