Relation between spin and orbital magnetism in excited states of ferromagnetic materials — •Leonid Sandratskii — Max Planck Institute of Microstructure Physics, Halle, Germany

Modern experiments are able to disentangle the time dynamics and temperature dependences of the atomic spin and orbital moments. The results appear to be strongly system dependent. The properties of the orbital moments are closely connected with the properties of the magnetic anisotropy that is the physical quantity of enormous practical importance. And again the experiments on the temperature dependence of the magnetic anisotropy of the itinerant-electron magnets show strongly system dependent behavior and the absence of any universal behavior. By studying the properties of excited states of Fe, Co, CoPd, FePt films and uncapped and capped Co/Pd(001) we shed the light on the origin of the diversity of behavior.
