Abstract

Three-dimensional nanoscale structures of lead were fabricated by electrodeposition of pure lead into artificial porous opal. The size of the metallic regions was comparable to the superconducting coherence length of bulk lead. T_c as high as 7.36 K was observed, also dT_c/dH was 2.7 times smaller than in bulk lead. Many of the characteristics of these differ from bulk lead, a type I superconductor. Irreversibility line and magnetic relaxation rates (S) were also studied. S(T) displayed two maxima, with a peak value about 10 times smaller than that of typical high-T_c superconductors.
