  Hole and electron doped LaCoO3 is studied using dynamical mean-field theory.
The one-particle spectra are analyzed and compared to the available
experimental data, in particular the x-ray absorption spectra. Analyzing the
temporal spin-spin correlation functions we find the atomic intermediate spin
state is not important for the observed Curie-Weiss susceptibility. Contrary to
the commonly held view about the roles played by the t2g and eg electrons we
find narrow quasiparticle bands of t2g character crossing the Fermi level
accompanied by strongly damped eg excitations.
