Abstract Magnetic nanoparticles have been proposed as contact-free minimal-background nanobarcodes, and yet it has been difficult to rapidly and reliably decode them in an assembly. Here, high aspect ratio nanoparticles, or magnetic nanowires (MNWs), are characterized using first-order reversal curves (FORC) to investigate quantitative decoding. We have synthesized four types of nanowires (differing in diameter) that might be used for barcoding, and identified four possible “signature” functions that might be used to quickly distinguish them. To test this, we have measured the signatures of several combination samples containing two or four different MNW types, and fit them to linear combinations of the individual type signatures to determine the volume ratios of the types. We find that the signature which determines the ratios most accurately involves only the slope of each FORC at its reversal field, which requires only 2–4 data points per FORC curve, reducing the measurement time by a factor of 10 to 50 compared to measuring the full FORC.

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.
