“…In the last years, studies on ferromagnetic-nonmagnetic multilayer nanowire arrays and binary systems, including CoCu, FeAg, CoAg, CoPd, and CoPt, have been reported in the literature [4][5][6][7] due to their interesting magnetic and magnetotransport properties.…”

Arrays of hexagonally ordered Fe 28 Co 67 Cu 5 nanowires with tailored diameter from 18 to 27 nm were prepared by electroplating into anodic alumina templates and annealed in the temperature range of 300-600 C, preserving but refining their bcc crystal structure. Despite the partial reduction of saturation magnetization and corresponding shape anisotropy after annealing at 500 C, larger coercivity, 0.36 T, and squareness ratio, M r /M s ¼ 0.98, were obtained. This unexpected behavior is interpreted through micromagnetic simulations where the magnetic hardening is associated with the transition from vortex to transverse domain-wall reversal modes connected with the reduction of saturation magnetization. Simulations also predict a significant coercivity increase with decreasing nanowires diameter which agrees with experimental data in the overlapping diameter range. V C 2013 AIP Publishing LLC.

“…Magnetic and nonmagnetic multilayer metal systems have been investigated for giant magnetoresistance (GMR) behavior; 1,2) however, there has been little research on the NiAg alloy system because of the alloying characteristics of these metals. Interestingly, the phase diagram 3) confirms that the two metals are totally immiscible, and intermetallic phases were not observed at low temperature.…”

Electrodeposition of Silver-Nickel Thin Films with a Galvanostatic Method

NiAg thin films were deposited by galvanostatic electrodeposition in an electrolyte containing NiSO 4 , AgNO 3 and C 6 H 5 Na 3 O 7 . The variation of composition and crystallography of electrodeposited NiAg thin films with current density and electrolyte concentration was investigated. At a low current density, electrodeposition of silver was dominant, which could be induced by a comparably low reduction potential. However, nickel electrodeposition became the dominant component at a higher current density because of the mass transfer limitation of Ag ions. When 50 mA/cm 2 was applied, the FCC (200) phase was observed, which implies significant enhancement of the nucleation rate by increasing the reduction potential at a high current density condition.

“…Pore size and depth affects solution mass transfer, with more slowly diffusing or less concentrated cation species depositing more slowly as pore aspect ratio increases [88]. In spite of these limitations a wide range of alloys was reported with good control over composition [88,[252][253][254][255][256].…”

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.
