Abstract
CoCu alloy nanowire arrays were ac-pulse electrodeposited into porous anodic aluminum oxide. The effect of off-time between pulses and Cu concentration on the magnetic properties, crystalline structure and weight percentage of CoxCu1−x alloy nanowires have been studied by alternating gradient force magnetometer (AGFM), X-ray diffraction pattern (XRD) and energy dispersed spectrometry (EDS), respectively. Increasing the off-time between pulses decreased the weight percentage of Co in the range of (x=0.84−0.24). Results of EDS were in accordance with saturation magnetization per unit area of the samples. Coexistence of a moderate off-time and Cu concentration provided excellent conditions for fabrication of the composite nanowires which were proved by XRD patterns.
