• 論文の詳細を見る

• The nuclear spin lattice relaxation rate, T , ', for "Cu in zero field from 8 K downto 0.3 K, has been measured in Nb-Cu multilayered thin films where both the Nb- andCu-layer thicknesses are much smaller compared to the coherence lengths. A BCS-like temperature dependence of T . ' replaced gradually by a Korringa-law-like one atlow temperatures has been found. A dependence of the relaxation on the Cu-layerthickness at low temperatures has also been found. It has been proposed and confirmed by a series of experiments that superconductivity in the Cu-layer induced bythe proximity effect has an anisotropic energy gap, reflecting the geometrical featureof a thin film.[superconducting proximity effect, energy gap, superconducting multilayers, ll Nb-Cu, "Cu NMR, spin-lattice relaxation ratel
