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.}, cin = {PGI-1 / IAS-1 / JARA-FIT}, ddc = {530}, cid = {I:(DE-Juel1)PGI-1-20110106 / I:(DE-Juel1)IAS-1-20090406 / $I:(DE-82)080009_20140620$}, pnm = {142 - Controlling Spin-Based Phenomena (POF3-142)}, pid = {G:(DE-HGF)POF3-142}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000349247900003}, doi = {10.1103/PhysRevB.91.075405}, url = {https://juser.fz-juelich.de/record/189765}, }
