Abstract
We have carried out Nb-93 and Cu-63 NMR measurements in Nb/Cu supercon ducting multilayered thin film down to 0.1K, and measured nuclear spin lattice relaxation rate (1/T-1) in zero field using the field cycling method. The temperature dependence of 1/T-1 has shown the existence o f the superconducting energy gap with the magnitude of 3.5k(B)T(C) in Nb layers and a smaller energy gap in Cu layers induced by the superco nducting proximity effect.
