contents	Contribution of the Spin Current to the Damping of the Magnetic Moment Precession of Fe Impurities in Pd M. V. Tovar Costa A. C. de Castro Barbosa A. T. Costa Física, Astronomía y Matemáticas Spin waves Spin current Giant magnetic moment We investigate the spin dynamics of a magnetic adatom on a non-magnetic surface with strong Stoner enhancement.We find a strong damping of the adatoms magnetization precession and a large shift of the resonancefrequency from its bare value. Stoner enhancement in the substrate reduces the damping. We explore thedamping dependence on features of the electronic structure. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436513 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3B Vol.36
