Abstract
Magnetic-ion concentration dependence of some physical quantities in heavy-fermion systems are investigated on the basis of the periodic Anderson model with randomly distributed sites without f electrons. A scheme consisting of the dynamical mean-field theory and the coherent-potential approximation is applied to calculate the density of states, the resistivity, and the specific heat. By the present scheme, both the heavy Fermi liquid in heavy-fermion systems and the local Fermi liquid in dilute Kondo impurity systems can be studied on the same footing.
