“…Based on these results, it is obvious that crystal structure of the arrays of (Fe 30 Co 70 ) 100−x Zn x (x ≥ 5) NW alloys gradually change from bcc crystalline phase to amorphous phase with an increasing Zn content, which is in agreement with recent reports [30]. Further increase in the Zn content significantly reduces the Ms of the NW arrays, resulting in a strong deterioration in both Hc and Sq.…”

“…The peak in the nanowire with 2% Zn is higher than other nanowires and this shows that without Zn, the nanowire structure is bcc and Zn makes it highly ordered. As it can be seen, the as deposited Fe 30 Co 70 (x = 0) NWs has bcc structure with (1 1 0) axis, indicating that the NWs axis is along this axis. The intensity of the peaks for (Fe 30 Co 70 ) 99 Zn 1 (x = 1) NW sample is lower, indicating that the crystallinity decreases due to the presence of Zn.…”

“…The Hc and Sq signicantly decrease from 2032 Oe and 0.95 for Fe 30 Co 70 (x = 0) sample to about 560 Oe and 0.66 for (Fe 30 Co 70 ) 90 Zn 10 (x = 10) sample, respectively. It is known that the Hc depends on the magnetization reversal process.…”

(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.

“…Fabricated high surface area electrode provides greater currents and longer viability of the battery. Magnetic properties of nanowires made of ferromagnetic materials are intensively researched [193,210,239,23,284,65,259,38,258,216,12,64,275,83,61,191,180,81]. Also optical properties [56, 95,102,283], as well as catalytic properties [148,307], attract the attention of the researchers.…”

Anodic aluminum oxide (AAO) consists of parallel pores arranged in a honeycomb-like array. Since a two-step self-organized approach in anodic alumina fabrication was invented, tremendous attention was paid to this material. Structural features of anodic alumina, like pore diameter, interpore distance, and nanoporous oxide thickness, can be fully controlled by operating conditions, including type, concentration and temperature of the electrolyte, applied voltage, and duration of the anodization process. Moreover, these operating conditions have also a major impact on the nanoporous array arrangement. Quantitative arrangement analysis methods employing fast Fourier transforms have been developed to assess the nanopores' arrangement. The most frequent application of the anodic aluminum oxide is a template-assisted fabrication of nanostructures. Templates made of the AAO are being successfully applied in fabrication of nanowires, nanotubes, and nanodots by using diversity of techniques, including electrochemical deposition, physical and chemical vapor deposition, sol-gel techniques, etc. Due to the size of obtained nanostructures, magnetic, electric, piezoelectric, luminescent, and catalytic properties of the deposited materials can be significantly improved. Thus, control of the nanopores' structural features and arrangement is crucial for AAO applications in nanotechnology.

“…Among magnetic nanowires, magnetic and nonmagnetic Co based alloys have been more interested because of its uniaxial crystal structure. There have been numerous reports studying the microstructures and magnetic properties of Co based alloys such as CoFe [12], CoNi [13], CoCu [14], CoPt [15,16], CoPd [17,18], CoPb [19,20] and CoZn [21,22]. In the present work in a constant electrolyte, CoZn nanowires with various Zn contents were synthesized by varying the off time between pulses of the ac pulse electrodeposition voltage.…”
