The spin-lattice relaxation rate [ital W] on [sup 205]Tl has been measured in the mixed state of a Tl[sub 2]Ba[sub 2]CuO[sub 6] aligned powder sample with [ital T][sub [ital c]]=100 K. At [ital T][lt]25 K, [ital W][proportional to][ital T] and decreases with increasing magnetic field. This behavior is explained as caused by fluctuations of pancake vortices; the latter induce a time dependent random magnetic field which causes the relaxation of nuclear spins.
