Abstract
The nuclear spin-lattice relaxation rate, T1-1, for 63Cu in zero field from 4.2K down to 0.3K, has been measured in a series of NbCu multilayers. A BCS-like temperature dependence of T1-1 followed gradually by A Korringa-law-like one at low temperatures, has been found. It has been confirmed that such behavior of T1-1 comes from the anisotropic energy gap in the Cu-layers.
