CoXPt1-X alloy nanowires were fabricated by electrochemical template synthesis from a solution containing both Co(II) and Pt(II) ions. Over a wide range of deposition conditions, single-phase, fcc CoXPt1-X alloy nanowires were obtained. The nanowires exhibit both shape and magnetocrystalline anisotropy leading to large coercivity and high remanence along the wire axis. The magnetocrystalline anisotropy constant Ku was determined for 〈111〉 textured nanowires.
