Magnetic nanoarrays on flexible substrates.

Abstract

In this work, we used nanosphere lithography to fabricate large area 2-D magnetic nanoparticle (MNP) arrays on a flexible polyimide substrate (Kapton). Samples were fabricated by assembling polystyrene (PS) spheres on thin films of Co capped with Au. Etched PS spheres were used to mask Co-Au particle arrays. The MNP arrays were subjected to superconducting quantum interference device measurements; flat samples (10 nm Co coated with 10 nm Au) exhibited an M _s of 117.3 emu g^-1, which was lower than the reported literature value for bulk Co (162.7 emu g^-1). When compared to the flat film, coercivity, H _c, increased in a linear fashion with respect to particle size. These preliminary results reveal that future investiga
