Abstract.
In this work, CoFe/Cu multilayer nanowires were deposited into an anodic aluminum oxide template using the single-bath method. The effect of deposition parameters as off-time between pulses and reduction/oxidation voltage of both the magnetic CoFe and non-magnetic Cu layers on the magnetic behavior of the multilayer nanowires was investigated. The layers thickness was controlled through the pulse numbers: 30, 50, 100, 200, 400 and 600 pulses were used to deposit the CoFe layers, while 200 and 400 pulses for the Cu layers. Due to the shape variation of the CoFe layer from rod- to disc-like cylindrical (rotation of the magnetic easy axis toward the plane of the disc), decreasing the CoFe pulse numbers led to approaching the in-plane coercivity toward the out of plane. The structural studies revealed that the pulsed alternating electrodeposition method in the single-bath system enabled to deposit CoFe/Cu multilayer nanowires with highly pure segments.
