Abstract: Passive iron-oxide nanocrystals are grown on Fe(100) and Fe(110) facets of single-crystal Fe whiskers. Transmission electron microscopy and electron diffraction characterize the oxide spinel structure and their epitaxial growth on Fe whiskers. Iron-oxide nanocrystals grown on Fe(100) facets have sizes close to that of the single magnetic domain Fe<subscript>3</subscript>O<subscript>4</subscript> particles, which is supported by our preliminary magnetic force microscopy measurement at room temperature. © 2004 American Institute of Physics.
