Abstract
New phases and new morphologies are obtained for the magnetic elements by epitaxial growth on suitably prepared substrates. The tools of surface science and ultra high vacuum make possible the engineering of magnetic materials on an atomic scale. Epitaxy provides negative pressure for enhanced magnetic moments. Reduced symmetry at surfaces produces enhanced anisotropy, particularly through antisymetric exchange, Dzialishinski-Moriya, interactions. Reflection High Energy Electron Diffraction is used to characterize and control the deposition of Ni, Fe, and Mn on substrates of Ru, Fe, and Ag. Fe whiskers are particularly good substrates for studies of growth processes.
