CRYSTAL-FIELD EFFECTS IN NEW KONDO-LATTIC E CENIGA2

Electrical resistivity, thermopower and magnetic susceptibility of sol id solutions of substitution for basic compound CeNiGa2, which is a ne w Kondo lattice with the particularly sharp correlation thin structure g(f)(E) near Fermi level, was investigated. It is shown that the stru cture g(f)(E) is determined by mutual location of the crystal field ex cited 4f-sublevels of Ce(Delta(1), Delta(2)) and their Kondo interacti on with the conducting electrons. In this case there is a definite cor relation (T-K(HT) << Delta(1) approximate to approximate to T-K(BT) << Delta(2), where T-K(HT), T-K(BT) are low and high temperature values of Kondo temperatures ) between the characteristic parameters of the K ondo f-centre.
