Zusammenfassung

The topic of the project centers on the theoretical and experimental investigation of the Electron Spin Resonance (ESR) phenomenon in heavy electron systems. In a preceding project the ESR in the Kondo lattice system YbRh2Si2 could be explained via a so called "Kondo Coupled Spin Mode". The theoretical work of the new project will treat the influence of ferromagnetic correlations on the ESR linewidth. The interplay of Kondo coupling and RKKY interaction will be elucidated as well as extraordinary anisotropies of ESR-parameters. Also, for this purpose new experimental results of Cerium ...
