Description
Summary:The present paper examines the influence of an applied magnetic field B (AMF B) on the physical and chemical properties of electrodeposited Cobalt (Co) and Nickel (Ni) nanowires into anodic aluminum oxide (AAO) membranes. The deposition potential and the effect of the AMF B on the mass transport rate of Ni and Co ions to the bottom of the pores were examined using cyclic voltammetry (CV) and current density–time curves. X-ray diffraction (XRD) studies show that the AMF B promotes the growth of Co and Ni into the membrane pores. The AMF B effect on the morphology and chemical composition of the electrodeposited nanowires were studied by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDXS), respectively. Co nanowires exhibit a high coercive field Hc, shape anisotropy, and squareness ratio MMs than those corresponding to Ni nanowires. [Display omitted] •Successful magnetoelectrochemical synthesis of Co and Ni nanowires on AAO membranes.•The XRD analysis reveal the growth of highly crystalline and textured Co and Ni nanowires.•The electrochemical deposition with an AMF B enhances the average atomic percentage of Co and Ni metals into the AAO membrane pores.•The magnetoelectrodeposition of Co and Ni nanowires that exhibit high shape anisotropies and large hysteresis loops.
