- 論文の詳細を見る
Nuclear spin-lattice relaxation times T of "'La in high-7'. superconductor (La. .Sr,).Cu0. (,X'=0.075, 0.10) have been measured in zero field. T. ' in the superconducting state decreases rapidly, indicating a superconducting energy gap formation, butno signs of T7 ' enhancement are observed just below IC. T . ' in the normal stateshows slightly stronger temperature dependence than that expected from the Korringarelation (7'.7'=const,) observed in a highly Sr-doped, nonsuperconducting com-pound with ,X'=0.15.
