Understanding the great range of magnetic ordering behavior in correlated f-electron systems.

Proposes a theory which organize the diverse magnetic behavior into a unified picture describable through one Hamiltonian model. Approaches used in treating the correlated f-electron systems; Concept of Kondo resonance-Kondo compensation; Key elements of the Kondo problem; Description of the atomic Hamiltonian; Information on the two-component spectrum near the Fermi level.
