Abstract
The spin-lattice relaxation rate W on Tl-205 has been measured in the mixed state of a Tl2Ba2CuO6 aligned powder sample with T(c) = 100 K. A t T < 25 K, W is-proportional-to T and decreases with increasing magne tic field. This behavior is explained as caused by fluctuations of pan cake vortices; the latter induce a time dependent random magnetic fiel d which causes the relaxation of nuclear spins.
