Abstract

The application of Raman scattering to intermetallics is shown to be particularly rewarding in the case of intermetallic compounds of the rare earths, exhibiting Kondo or intermediate valence behavior. Unlike in other materials, a detailed, localized electronic structure is revealed for the first time by electronic Raman scattering, such as 4f crystalline electric field excitations, 4f intraconfigurational spin-orbit split multiple levels and interconfigurational excitations between 4f configurations involved in the valence fluctuation 4fn⇌4fn−1+e−1 (EF). As an outstanding example we discuss the intermediate valence compound EuPd2Si2.
