Abstract
Cu-63 and Nb-93 NMR have been carried out in Nb/Cu superconducting mul tilayered thin film down to 0.1K, and nuclear spin lattice relaxation time, T1, in low field (H=100 Oe) has been measured by using field cyc ling method. 1/T1 of Cu-63 has a coherence peak just below Tc and decr eases at low temperatures. The value of 1/T1 at low temperatures incre ases with increasing the mean free path of electrons in the Cu layers.
