Abstract

Hexagonal CePd2-xNixAl3 exhibits a crossover from a Kondo lattice showing magnetic order at TN [similar, equals] 2.8 K for x [less-than-or-equals, slant] 0.2 to intermediate valence (IV) for x [rightwards arrow] 2. Though TN(x) is weakly affected upon Pd/Ni substitution before vanishing at finite temperature, the Kondo temperature TK progressively increases. Above x [similar, equals] 0.3 the phase boundary no longer exists and strong spin fluctuations cause pronounced deviations from a Fermi-liquid ground state before the IV regime is established for x [gt-or-equal, slanted] 1.
