Ni, Co and Fe nanowires were synthesized into nanoporous polycarbonate films to investigate the growth rates and the crystal structures. A polycarbonate membrane filter with numerous cylindrical nanopores was used as a template for the nanowires growth. The pore size was as followings: pore-diameter of 150 nm, pore-length of 6000 nm, and pore-density of 10⁸ pore·cm^-2. The nanowires were potentio-statically electrodeposited into the nanopores from an aqueous solution containing metal sulfate and boric acid. At the cathode potential of -1.0 V, the growth rate of Ni and Fe nanowires was around 6 nm·sec^-1, while that of Co nanowires was around 10 nm·sec^-1. The shape of electrodeposited nanowires was perfectly transferred from that of nanopores and the aspect ratio reached to almost 40. The each nanowire was consisted of single crystalline metal and the long-axis directions of each nanowire were fcc-Ni [111], hcp-Co [001] and bcc-Fe [210]. Basis on the shape anisotropy of nanowires, the magnetization easy-axis oriented to the longitudinal direction of nanowires, which corresponds to the perpendicular direction to the polycarbonate film plane.
