Abstract
Nuclear spin-lattice relaxation times T1 of 139La in high-Tc superconductor (La1-x Srx)2CuO4 (x=0.075,0.10) have been measured in zero field. T-11 in the superconducting state decreases rapidly, indicating a superconducting energy gap formation, but no signs of T-11 enhancement are observed just below Tc. T-11 in the normal state shows slightly stronger temperature dependence than that expected from the Korringa relation (T1T= const.) observed in a highly Sr-doped, nonsuperconducting compound with x=0.15.
