(a) Schematic representation showing the deposition of a 10 nm thick insulating layer and of a 25 nm thick NbN film on the extremities of an array of Ni nanowires embedded in a nanoporous alumina template. (b) SEM image of the surface of the filled template after the polishing step. The inset shows the AFM picture of the surface after the evaporation of the insulating layer.
(a) Magnetoresistance curve at for a 25 nm thick NbN film on top of an array of 75 nm in diameter Ni nanowires . Top inset: same magnetoresistance curve at . Bottom inset: derivative of the curve obtained at . (b) Superconducting to normal state transition line for a 25 nm thick NbN film deposited on top of an array of 60 nm in diameter Co nanowires (solid line) and on a flat sapphire substrate (dotted line).
(a) Magnetoresistance curves for a 25 nm thick NbN film on 60 nm diameter Ni nanowires array at . The field was swept from positive to negative saturation (solid curve) and from negative to positive saturation (dotted curve). (b) Corresponding magnetization curve of the same sample above .
