Unique Capability

Magnetic nanowire arrays formed by templated electrodeposition are a promising way of making ultra-high density magnetic recording media. We have used both Poly Carbonate Track Etched (PCTE) and Anodic Aluminum Oxide (AAO) membranes to obtain Cobalt nanowires. Also by suitably adjusting the electrodeposition process, hollow Cobalt nanotubules were formed. The hollow cylindrical structure gives a unique capability to tailor their magnetization. The morphology of the samples was investigated using SEM and TEM. Magnetic characterization done using SQUID shows the influence of morphology and that the nanotubules have rather different switching behaviour than solid nanowires. Finite element micromagnetic modeling was performed of a single nanowire, a single nanotubule and also arrays of nanotubules. The calculated static M-H curves were found to match closely the SQUID measurements. The coercivity increases with length while the inner and outer diameters greatly affect rotational switching of the magnetization.
