Abstract

Inverse opal polymer replicas serve as excellent templates for the formation of metal sphere arrays (see Figure). Here nickel sphere arrays have been prepared by electrodeposition into poly(methyl methacrylate) templates. Angle-dependent magnetic measurements indicate that these properties are dominated by shape anisotropy.
