Abstract
Thermodynamic properties of the one-dimensional supersymmetric t-J mod el are investigated by means of the Bethe ansatz method. For an arbitr ary electron concentration, the magnetic susceptibility, the charge su sceptibility and the specific heat are calculated numerically as a fun ction of temperature. The results are discussed in comparison with the thermodynamic properties of the one-dimensional Hubbard model.
