Effects of Environment on the Electronic Configuration in Intermediate Valent Rare Earth Systems

摘要: In the intermediate valence problem one must consider highly correlated localized f electrons in presence of delocalized d and s (denoted for simplicity). Two configurations, fndm fn−1dm+1, have comparable energies be considered. It is possible that a completely electronic theory, such as Anderson/Kondo impurity/lattice models, may contain essence coupling these states will describe magnetic susceptibility specific heat. However, configurations different sizes bonding properties. The proper configuration depend and, conversely, major influence on structure. this paper we discuss relationship to volume, homogeneous transitions, surface local existence gaps density states.
