摘要
In order to investigate the interrelation between the superconductivity and the antiferromagnetic spin correlation, we have measured the nuclear-spin lattice relaxation time T1 and the spin echo decay time T2 of 63Cu in (La1−xSrx)2CuO4 for x=0.05, 0.065 and 0.075 with Tc = 27 K, 36 K and 38 K, respectively. Both relaxation rates, 1/T1 and 1/T2, being enhanced with decreasing Sr content, is found to be due to the development of the low frequency antiferromagnetic spin fluctuation. © 1990, Elsevier Science Publishers B.V.
