English abstract:
Low-Temperature Specific Heat of Ce-Ni-Ge Compounds and Their Nonmagnetic Analogues

The specific heat of CeNiGe3, Ce2Ni3Ge5, Ce3NiGe2 and Ce3Ni2Ge7 and their isostructural analogues with La or Y was studied in the temperature range 2.5--70 K. For all the Ce-based compounds Cp(T) exhibits pronounced \lambda -shaped peaks at the magnetic phase transitions. In the paramagnetic range Kondo and Schottky terms notably contribute to the total specific heat. In the ordered region, Cp(T) is dominated by a spin-wave contribution. The characteristic Kondo and RKKY energy scales in all the compounds are estimated to be of similar magnitude.
