Itinerant Nature of Atom-Magnetization Excitation by Tunneling Electrons
Abstract
We have performed single-atom magnetization curve (SAMC) measurements and inelastic scanning tunneling spectroscopy (ISTS) on individual Fe atoms on a Cu(111) surface. The SAMCs show a broad distribution of magnetic moments with [3.5]μ B being the mean value. ISTS reveals a magnetization excitation with a lifetime of [200]fsec which decreases by a factor of two upon application of a magnetic field of [12]T. The experimental observations are quantitatively explained by the decay of the magnetization excitation into Stoner modes of the itinerant electron system as shown by newly developed theoretical modeling.
