摘要：

The electrical resistivity rho(T) of the intermediate valence compounds YbInAu2 and YbCuAl was investigated up to 8 GPa. With increasing pressure, the Kondo temperature decreases and the residual resistivity po increases. At low temperature, rho(T) shows a Fermi liquid behaviour in YbCuAl whereas it develops a minimum in YbInAu2. These findings are discussed in terms of the Kondo lattice disorder.
