Electrochemical deposition of nickel nanowire arrays in single-crystal mica films

Abstract
Nanopores with lateral dimensions as small as 30 nm have been fabricated by nuclear track etching in 5 μm thick, single-crystal muscovite mica wafers. The nanopores have a diamond shape with their axes aligned with the crystal axes of mica as a result of anisotropic etching. Nickel nanowire arrays have been fabricated by electrodeposition into the nanopores. The magnetic properties of the nanowire arrays are compared with those fabricated in polymer membranes.
