Magnetic properties investigation through off-time between pulses in Ni nanowire arrays

Abstract

Ni nanowire arrays were embedded in anodic aluminum oxide (AAO) template by alternative current pulse electrodeposition technique. Samples were prepared with different off-times between pulses in electrolyte containing 0.3 M NiSO4. The effect of off-time on the coercivity and magnetization of prepared nanowires was investigated. The obtained results show, with increase the off-time initially to 10ms off-time, the magnetic properties content increased and then were reduced.
