Intrawire magnetic interactions in electrodeposited Co/Cu and Co/Au multilayer nanowires

Driven by the demands for ever increasing storage density and low-powered spintronic devices, arrays of ferromagnetic nanowires have been studied as candidates for patterned magnetic recording media [1-2], especially towards three-dimensional structure that can potentially drastically increase the storage density [3-4]. In addition, multilayer nanowire arrays in which each wire has a combination of alternating magnetic and non-magnetic layers are very useful for the application of giant magnetoresistance (GMR) with the current perpendicular to the plane. For the arrays of the nanowires to be useful in patterned magnetic area, it is important to understand the characteristics of these closely packed nanowires with the magnetization perpendicular to the plane.
