Spin vs charge excitations in heavy-fermion compounds*
Abstract
Description
It is pointed out that the answer on the question about the role played by spin and charge excitations will help to solve the physical origin of the heavy- fermion phenomena. Our answer is that neutral spin-like excitations are responsible for the heavy-fermion phenomena whereas the role of the charge excitations is negligible.
Keywords: heavy fermion, spin excitations, charge excitations
