Highly ordered 14 nm diam cobalt platinum alloy nanowire arrays with Pt content ranging from 9 to 86 at. % have been electrodeposited into nanoporous anodic aluminum oxide templates. The crystal structure of the as-deposited Co1-xPtx nanowire arrays changes progressively from hcp to a mixture of hcp and fcc phases and finally to pure fcc with increasing Pt content. The coercivity, squareness, and saturation magnetization of the as-deposited nanowire arrays have been investigated as a function of nanowire composition. [ABSTRACT FROM AUTHOR]
