Preparation and magnetic properties of cylindrical permalloy nanowire arrays

Cylindrical permalloy nanowire arrays are prepared by employing anodic aluminum oxide (AAO) template-assisted electrochemical deposition method. To prepare high-quality permalloy nanowire, the effects of different deposition parameters (pulse current density, concentration and pH value of the electrolyte, and deposition temperature) on the chemical composition, uniformity, and magnetic properties of the nanowires are systematically investigated. A high-quality permalloy nanowire with good magnetic properties of M-S approximate to 5.7 x 10(5) A/m and alpha approximate to 0.04 has been successfully prepared by optimizing the preparation scheme, which can provide technical support for mass production of cylindrical permalloy nanowire for spintronic devices.
