Abstract

Programmable defect-free self-assembled magnetic nanowire arrays were produced by using specially designed nano-magnet arrays and external magnetic field. Nickel nanowires were grown on nanoporous template using electrodeposition technique. Magnetic properties, structure and morphology were studied carefully by using vibrating sample magnetometer (VSM), X-ray diffraction (XRD), and scanning electron microscopy (SEM). Individual magnetic nanowires were successfully trapped between the nanomagnet pairs with a width of 200 nm and a thickness of 100 nm. Templated self-assembly of magnetic nanowires was successfully demonstrated with Permalloy nano-magnet arrays in both 1D and 2D.
