abstract = {The dynamical transverse magnetic Kohn-Sham susceptibility
calculated within time-dependent density functional theory
shows a fairly linear behavior for a finite energy window.
This observation is used to propose a scheme where the
computation of this quantity is greatly simplified. Regular
simulations based on static density functional theory can be
used to extract the dynamical behavior of the magnetic
response function. Besides the ability to calculate
elegantly damping of magnetic excitations due to
electron-hole excitations, we derive along the way useful
equations giving the main characteristics of these
excitations: effective g factors and the resonance
frequencies that can be accessed experimentally using
inelastic scanning tunneling spectroscopy or spin-polarized
electron energy loss spectroscopy.},
