“…Further increasing the pH value of electrolyte to 5.5, the fabricated Ni nanowire arrays exhibit a single peak which can be indexed to Ni (220), suggesting a good [220] fiber texture, while the intensity of the (220) peak is slightly lower than that in Figure 4(c). The full width at half maximum (FWHM) of (220) peaks in Figures 4(c) and 4(d) is measured to be both about 0.09°, and the average grain size evaluated by Scherrer equation [11] is about 64.8 nm, close to the pore size of the AAO templates.…”

Highly textured Ni nanowire arrays were fabricated into anodic aluminum oxide (AAO) templates by pulse DC electrodeposition. The applied voltage and pH value of electrolytes were found strongly affecting the microstructure and magnetic properties of Ni nanowire arrays. Low applied potential and pH value both prefer to form polycrystalline fcc Ni nanowires. Increasing the applied potential or pH value favors the Ni [220] texture and even eventually forms the [220] oriented single crystal Ni wires, while exorbitant potential and pH value will conversely weaken the texture of nanowires. The magnetic properties of Ni wires are closely related to the microstructure of Ni nanowire arrays and large coercivities more than 1000 Oe were achieved at single crystalline Ni nanowire arrays. The mechanisms for the effect of applied potential and pH value on the grain size, texture and magnetic properties of Ni nanowire arrays have been discussed. nanowire arrays, applied potential, pH value, microstructure, magnetic properties, electrodeposition PACS: 07.55.-w, 07.55.Jg, 07.50.-eElectrodepositing elements into anodic alumina oxide (AAO) templates provides a simple technique to obtain the highly ordered nanowire arrays [1-3]. The low-cost AAO films are thermally stable at high temperature and the pore channels they contain are of uniform size, parallel to each other and perpendicular to the film surface. Furthermore, it is also comparatively easy to control the wire dimensions and the areal density of pores by adjusting the anodizing parameters (e.g. voltage, electrolytes and temperature) [1,2]. These features have attracted considerable interests in recent years due to the potential applications in ultra-highdensity magnetic recording, catalysts, nanoscale electronic and optoelectronic devices [4,5]. However, a well-controlled growth of nanowires is necessary for the successful application in devices. Tian et al. [6] have reported that if lower overpotential is used during DC electrodeposition then single crystalline nanowires of noble metals such as Au, Ag, Cu can be grown, but it is difficult to grow single crystalline nanowires of high melting point metals such as Co, Ni, Rh. Nevertheless, Yue et al. have found [7] that the lower potential is essential for the growth of single crystalline Ni nanowire arrays. Conversely, Pan et al. [8] and Thongmee et al. [9] have indicated that a higher overpotential favors the growth of single crystalline nanowires of Ni, Zn, Cu and Co. Clearly, the formation of single crystalline nanowires is not as easily explained only by overpotential. In recent literature, Kockar et al. [10] have reported that the magnetic properties of continuous Ni films are very sensitive to the electrolyte pH value. However, up to now, there are relatively few reports [7] studying the effect of pH value on the structure and magnetic properties of Ni nanowires. In this work, we investigated the influences of both potential and pH value on the microstructure and magnetic properties of Ni nanowire arrays by pulse ...

“…Generally, mass transfer always affects the electrochemical reactions in a great extent, thus the size of electrodeposits can be easily controlled at micrometer or larger scales, but is hard to control at nanometer or smaller scales. From the viewpoint of the size of electrodeposits, the formation of nanosized electrodeposits such as nanoparticles and nanorods was often reported [2][3][4][5][6]. However, from the viewpoint of the size of reaction space, the behavior and the mechanism of metal electrodeposition in nanosized spaces such as in mesopores are not well understood.…”

Anodic aluminum oxide (AAO) with highly ordered nanoscale pores which are monodisperse and mutually parallel can be produced through a self-organized electrochemical process. Subsequent deposition of materials into the nanopores produces AAO embedded nanowire arrays. Whilst the templates can be further removed to obtain free individual nanowires, the embedded nanowires form an interesting nanocomposite structure. Recent research activities on the fabrication and characterization of AAO template based magnetic nanowires are reviewed in this article. Studies of specific systems are given as an example of the research in the area. anodic aluminum oxides, electrochemical deposition, magnetic nanowires, templates, magneto-optical propertiesPACS: 75.75.+a, 81.07.-b, 82.45.Aa, 75.50.-y Using a diverse range of fabrication techniques, magnetic nanostructures have been fabricated in a variety of forms: nanoparticles [1,2], nanowires [3], porous nanotubes [4] hollow spheres [5,6] and lithographically patterned films. In this article, we focus on magnetic nanowires fabricated using anodic aluminum oxide (AAO) templates.AAO templates are attractive in nanowire fabrication because of their excellent physical properties. The templates are regular, monodispersed and highly ordered (as shown in Figure 1) and are produced by a self-organized electrochemical process. The pore diameters (typically achievable in the range of 5 to 250 nm) and depths (a few nanometers to hundreds of micrometers) are controllable with high areal densities (10 8 -10 11 pores/cm 2 ), providing significant flexibility in the growth of nanowires with various diameters and aspect ratios. AAO templates are also transparent in the optical spectrum, from near ultraviolet (UV) to near infrared (IR), which makes them a suitable host for the investigation Figure 1 An electron micrograph showing highly ordered AAO template.of optical and magneto-optical properties of composite magnetic nanostructures. They are also thermally stable up to 900-1000°C, offering the possibility of thermal treatment of the magnetic nanowire arrays. In addition, they are corrosion-resistant and environmentally safe. Hence the templates have been used for producing nanowires of a very wide range of materials, including metals, semiconductors,
