Magnetic–optical bifunctional CoPt3/Co multilayered nanowire arrays |
(a) Cyclic voltammogram of deposition of CoPt3/Co NWs, Co NWs, and Pt NWs in a bath containing 2-M CoSO4 + 0.00375-M H2PtCl6 + 0.5-M H3BO3, containing 0.00375-M H2PtCl6 + 0.5-M H3BO3, and containing 2-M CoSO4 + 0.5-M H3BO3, respectively, scan rate = 50 mV/s; (b) the influence of deposition potential on Co–Pt atomic ratio. |
