We report on magnetic properties of well-ordered ultra-high density (1.25 × 1012/in2) arrays of vertically oriented high-aspect-ratio Co nanorods having a 14 nm diameter. The arrays were fabricated by electrodeposition within the pores of a nanoscale template derived from films of diblock copolymers. We find large coercivity enhancement (H c ≈ 3 kOe at 5 K and 800 Oe at 300 K) relative to a continuous Co film of comparable thickness. The high coercivity in our ordered arrays is contrasted with a distinct decrease of coercivity below ∼50nm rod diameter in a randomly positioned nanorod assembly. © 2001 Elsevier Science B.V.
