This paper reports the electrochemical synthesis and characterization of one dimensional hard magnetic CoPtP nanowires. Three electrode potentiostatic electrochemical technique was used to deposit nanowires into a nanoporous track-etched polycarbonate membrane with a nominal pore diameter 50 nm and thickness around 6-9 mu m. The room temperature electrolyte used for the deposition of nanowires consists of 60 gilt CoSO(4)7H(2)O, 4.1 g/lt H2PtCl6, 4.5 g/lt NaHPO2 and 25 g/lt B(OH)(3). The structural morphology was observed by scanning electron microscope and transmission electron microscope. The magnetic property of the nanowires was measured by vibrating sample magnetometer before removing the template. The coercive fields were measured to be 143 kA m(-1) and 103 kA m(-1) for parallel (H-vertical bar) and perpendicular to the nanowire axis, respectively. The higher coercivity value for H-vertical bar indicating nanowires' easy magnetization direction lies along the nanowires' axis. The average composition of the CoPtP nanowires was determined by electron dispersive spectroscopy and the crystallinity was measured by X-ray diffractometer. (C) 2012 Elsevier B.V.
