Abstract

Nuclear spin-lattice relaxation times T1 of 139La in high-TC superconductor (La1−xSrx)2CuO4 (x=0.075, 0.10) have been measured in zero field. T1−1 in the superconducting state decreases rapidly, indicating a superconducting energy gap formation, but no signs of T1−1 enhancement are observed just below TC. T1−1 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.
