Different self-assembled magnetic nanowire arrays were achieved with ∼100% trapping rate on templates with nanomagnet arrays under a low external magnetic field (∼10Oe). The principles of magnetic charge matching and dimension matching between the magnetic nanowires to be assembled and the gaps between two nanomagnets were proposed and demonstrated to be crucial for achieving low magnetostatic energy and high trapping rate. This templated self-assembly technique and the proposed template design principles have great potential for nanomanufacturing of regular arrays of magnetic nanostructures.
