Magnetic nanowires have attracted much attention for magnetic random access memory, spin torque devices and domain-wall movement controlled based spintronic devices. Template electrodeposition is an established and widely studied method for fabricating magnetic nanowires [1]. However, the diameter [2] or compositionally [3] modulated magnetic nanowires have been more recently exploited for versatile capability in manipulating domain wall movement. Here is this talk; we present two types of the two nanowire systems including (1) compositionally-graded FePt nanowires and (2) diameter-modulated nickel nanowires. FePt compositionally graded nanowires were fabricated by alternating current (AC) electrodeposition as one-pot method into anodic aluminum oxide (AAO) templates.
