Nanoporous alumina templates produced by two-step anodization technique with high purity aluminum (Al) sheets and oxalic acid electrolyte were used to synthesize FeXNi100-X nanowires via potentiostatic and galvanostatic electrodeposition methods (continuous or pulsed). Scanning and transmission electron microscopy and energy dispersive spectroscopy techniques were used to investigate pore filling, length and atomic composition of the nanowires. The main results showed that uniformity and homogeneity along the length of the nanowires depend on the applied electrodeposition methods, and only the galvanostatic ones enable uniform length along the whole nanoporous alumina template with atomic composition close to permalloy.
