      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
                      mu(B) being the mean value. ISTS reveals a magnetization
                      excitation with a lifetime of 200 fsec which decreases by a
                      factor of 2 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.},
