Abstract
In magnetic nanostructures, anisotropy directly influences formation of domains and their evolution with external field. Magneto-optic Kerr effect (MOKE) was used to study samples fabricated by templated electrodeposition of Cobalt into anodic aluminum oxide (AAO) templates. With proper conditions, both Co solid nanowire, as well as hollow nanotubule arrays, were formed. The morphology of the samples was investigated using SEM and AFM. Since as-deposited samples have high surface roughness, chemical mechanical polishing was used to polish the samples to achieve an optically flat surface. MOKE data show that shape anisotropy dominates along the long dimension and interaction effects between nanowires are important. A marked difference is seen between solid nanowires and hollow nanotubule samples, the latter showing formation of vortices.
