Growth and Characterization of Iron Nanowires Into Anodized Aluminum Oxide Templates Using Electrodeposition Technique
The Fe nanowires were prepared by Ac electrodeposition method. The two steps anodized aluminum oxides (alumina) were used as templates for electrodeposition of magnetic nanowires. Sulfuric acid was used to anodize aluminum. The pours diameter and growth rate of alumina were investigated. The FeSO4 electrolyte was used for growth of nanowires. The prepared magnetic nanowires were characterized b...
متن کاملMagnetic Properties of Fe49Co33Ni18Nanowire ArraysStudied by First-Order Reversal Curve Diagrams
Fe49Co33Ni18 nanowire arrays (175 nm in diameter and lengths ranging from 5 to 32μm) were fabricated into nanopores of hard-anodized aluminum oxide templates using pulsed ac electrodeposition technique. Hysteresis loop measurements indicated that increasing the length decreases coercivity and squareness values (from 274 Oe and 0.58 to200 Oe and 0.105, respective...
متن کاملMagnetic Properties of Ni0.3Fe0.7 Alloy Nanowires
The effect of length variation on the magnetic properties of NiFe alloy nanowires electrodeposited into the alumina template was investigated. The diameter (45±2.5 nm) and length (~ 1.9, 7.12, 8.3, 9.5 and 13.3 µm) of the nanowires were estimated from scanning electron microscopy images. Energy dispersive spectroscopy results showed Ni3Fe7 composition of the alloy nanowire...
متن کاملPerpendicular giant magnetoresistance of electrodeposited Co/Cu-multilayered nanowires in porous alumina templates
The giant magnetoresistance GMR of multilayered Co/Cu nanowires potentiostatically electrodeposited inside the pores of an anodized alumina template was studied in the current perpendicular to the plane CPP geometry. The maximum magnetoresistance change of 13.5% was observed for Co 8 nm /Cu 10 nm nanowires at room temperature. The interfacial roughness and/ or an intermixing between Co and Cu l...
متن کاملInvestigations of Magnetic Properties Through Electrodeposition Current and Controlled Cu Content in Pulse Electrodeposited CoFeCu Nanowires
CoFeCu nanowires were deposited by pulsed electrodeposition technique into the porous alumina templates by a two-step mild anodization technique, using the single-bath method. The electrodeposition was performed in a constant electrolyte while Cu constant was controlled by electrodeposition current. The electrodeposition current was 3.5, 4.25, 5 and 6 mA. The effect of electrodeposition current...
