Universality in heavy fermion systems with general degeneracy

We discuss the relation between the T-2 coefficient of electrical resistivity A and the T-linear specific-heat coefficient gamma for heavy-fermion systems with general N, where N is the degeneracy of quasiparticles. A set of experimental data reveals that the Kadowaki-Woods relation, A/gamma(2)=1x10(-5) muOmega cm(K mol/mJ)(2), collapses remarkably for large-N systems, although this relation has been regarded to be commonly applicable to the Fermi liquids. Instead, based on the Fermi-liquid theory we propose a new relation, (A) over tilde/(gamma) over cap (2)=1x10(-5) with (A) over tilde =A/(1)/N-2(N-1) and (gamma) over tilde=gamma/(1)/N-2(N-1). This new relation exhibits an excellent agreement with the data for the whole range of degenerate heavy fermions.
