Abstract :

Intermetallic systems with 4f or 5f electrons have often interesting thermodynamic properties at low temperatures. They behave like metals with very heavy charge carriers, i.e., their masses can be several hundred times the free electron mass. However, the heavy quasiparticle mass is disappearing as the temperature increases beyond a material dependent characteristic temperature Tk. We discuss different physical processes which may lead to heavy quasiparticle excitations and compare them with experiments.
