dc.descriptionThermodynamic and transport properties of CeNiIn2 are reported. The results indicate that this system undergoes a magnetic transition at T-C = 3.4 K. A Kondo temperature T-K = 2.7 K was also estimated. The electronic coefficient gamma approximate to 1 J/mol K-2, calculated from specific heat data, is characteristic for heavy-fermion systems and is consistent with the estimated T-K. For T < T-C, the specific heat and resistivity data are better described if an additional contribution from he spin waves with a gap in the magnon spectrum is considered. Crystal field parameters Delta(1) = 80 K and Delta(2) greater than or equal to 200 K were estimated from the temperature dependence of specific heat above T-C. The results obtained for this compound are explained as an interplay of the anisotropy and the competition between RKKY interaction and Kondo effect. (C) 2004 Elsevier B.V. All rights reserved.
