Transport properties of Ce(NixPd1-x)(2) Si-2

The electrical resistivity and the thermoelectric power of Ce(NixPd1-x)(2)S i-2 have been investigated. The chemical pressure effect caused by substitu tion of Pd with Ni on the electrical resistivity and the thermoelectric pow er was found to be very similar to the effect of hydrostatic pressure. The ground state of Ce(NixPd1-x)(2)Si-2 changes gradually from an antiferromagn etic Kondo state (x < 0.2) to an intermediate valence state (x > 0.3) with increasing x. The non-magnetic heavy fermion state seems to be realized at x approximate to 0.2-0.3. (C) 2001 Published by Elsevier Science B.V.
