abstract = {We present a first-principles theory of dynamical spin
excitations in the presence of spin-orbit coupling. The
broken global spin rotational invariance leads to a new sum
rule. We explore the competition between the magnetic
anisotropy energy and the external magnetic field, as well
as the role of electron-hole excitations, through
calculations for 3d-metal adatoms on the Cu(111) surface.
The spin excitation resonance energy and lifetime display
nontrivial behavior, establishing the strong impact of
relativistic effects. We legitimate the use of the
Landau-Lifshitz-Gilbert equation down to the atomic limit,
but with parameters that differ from a stationary theory.},
