Abstracts
Specific heat measurements have been performed on the polycrystalline TbNi_2, LaNi_2 and their solid solutions Tb_{1-x}La_xNi_2 (x=0.2, 0.3). The Debye temperatures, phonon and conduction electron contributions as well as the magnetic part of the heat capacity were determined and discussed. The magnetocaloric effect was estimated from measurements performed in a magnetic field of 0.42 T for TbNi_2, Tb_{0.8}La_{0.2}Ni_2 and Tb_{0.7}La_{0.3}Ni_2.
