Transport properties of Ce(NixPd1−x)2Si2

Abstract The electrical resistivity and the thermoelectric power of Ce(Ni x Pd 1− x ) 2 Si 2 have been investigated. The chemical pressure effect caused by substitution of Pd with Ni on the electrical resistivity and the thermoelectric power was found to be very similar to the effect of hydrostatic pressure. The ground state of Ce(Ni x Pd 1− x ) 2 Si 2 changes gradually from an antiferromagnetic Kondo state ( x x >0.3) with increasing x . The non-magnetic heavy fermion state seems to be realized at x ≈0.2–0.3.
