The magnetotransport properites of individual ferromagnetic nanowires (e.g. Ni, Co 23 Ni 77 , Ni 85 Fe 15 ) with 200 nm diameters were investigated. The ferromagnetic nanowires were successfully electrodeposited within an anodized alumina by controlling solution composition, temperature, and current density. Using a magnetic assembly technique, single nanowire was successfully bridged across microfabricated gold elecrodes. The temperature coefficient of resistance for ferromagnetic nanowires was lower than the bulk because of a larger residual resistance from increased electrical scattering in one‐dimensional structures. The ferromagnetic nanowires showed typical anisotropic magnetoresistance where the magnetoresistance ratio was lower than bulk values. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
