Abstract. Magnetic nanowires of Fe, Fe-Co, and Fe-Ni alloy and layered structure were prepared by electrochemical alternating current (AC) deposition method. The morphology of the nanowires in and without the matrix was studied by energy dispersive X-ray spectroscopy (EDX), scanning electron microscopy (SEM), and X-ray diffraction (XRD), respectively. The wires either show strong dependence on the combination of elements deposition (alloy or layered) or chemical composition (Co or Ni). The magnetic properties of the nanostructures were determined on the basis of Mössbauer spectroscopy (MS).

“…Nanowires Nanowires (NWs) are a key building block of nanotechnology and, are at the core of research efforts integrating them into novel devices. Metallic nanostructures provide a broad range of functionalities in electronic applications [84,85], magnetism [86][87][88], catalysis [87,89,90], biological tagging [91], photonics and plasmonics [92,93], and controlled self-assembly [94]. Integrating nanostructures into devices has many advantages such as a better utilization of precious metals, better control over the structure and thickness of adlayers, more effective electron pathways, and improved mechanical support.…”

A variety of nanostructured materials are produced through template-based synthesis methods, including zerodimensional, one-dimensional, and two-dimensional structures. These span different forms such as nanoparticles, nanowires, nanotubes, nanoflakes, and nanosheets. Many physical characteristics of these materials such as the shape and size can be finely controlled through template selection and as a result, their properties as well. Reviewed here are several examples of these nanomaterials, with emphasis specifically on the templates and synthesis routes used to produce the final nanostructures. In the first section, the templates have been discussed while in the second section, their corresponding synthesis methods have been briefly reviewed, and lastly in the third section, applications of the materials themselves are highlighted. Some examples of the templates frequently encountered are organic structure directing agents, surfactants, polymers, carbon frameworks, colloidal sol-gels, inorganic frameworks, and nanoporous membranes. Synthesis methods that adopt these templates include emulsion-based routes and template-filling approaches, such as self-assembly, electrodeposition, electroless deposition, vapor deposition, and other methods including layer-by-layer and lithography. Templatebased synthesized nanomaterials are frequently encountered in select fields such as solar energy, thermoelectric materials, catalysis, biomedical applications, and magnetowetting of surfaces.

“…Many attempts have been focused on the fabrication of NW alloys in order to improve the magnetic and mechanical of the NWs for practical application and to study performances the fundamental mechanisms behind the magnetic properties of these materials. For the case of FeCo, dierent NW alloys such as FeCo [1719], FeCoTb [20], FeCoP [2123], FeCoSi [24,25], FeCoPb [26] and FeCoNi [27] have been reported. In this work, we have fabricated and investigated the magnetic properties of FeCoZn NW alloys.…”

(Fe30Co70)100−xZnx (0 ≤ x ≤ 10) nanowires with diameters of ≈37 nm have been fabricated by AC electrodeposition into pores of anodized aluminum oxide (AAO) templates. The Fe30Co70 and Zn contents of the nanowires have been adjusted by varying the ratio of Fe30Co70 and Zn ion concentrations in the electrolyte. The eect of the Zn content and annealing on the magnetic properties (e.g., coercivity and squareness) of nanowires arrays have been investigated using X-ray diraction, scanning electron microscopy, and alternating gradient force magnetometer. X-ray diraction patterns reveal that an increase in the concentration of Zn ions of the electrolyte results in signicant reduction in coercivity and squareness. It was found that the magnetic properties of nanowires can be signicantly improved by appropriate annealing process. The highest values for coercivity (2670 Oe) and squareness (0.99) have been obtained for nanowires electrodeposited using 95/5 and 98/2 Fe30Co70:Zn concentrations at annealing temperatures of 575• C and 550• C, respectively.
