Description
The Bethe-Ansatz equations for the ground state of the Coqblin-Schrieffer model for j = 7/2 are solved for a special axial-crystal-field-splitting scheme. The occupations of the crystal-field levels, the specific-heat contribution linear in the temperature, and the magnetic susceptibility parallel and perpendicular to the crystal axis are obtained as a function of the crystal-field strength. The universality of the results is discussed and a comparison with experiments on YbCu2Si2 and YbCuAl is made
