摘要

We report the influence of external high-pressure (P up to 8GPa) on the temperature (T) dependence of electrical resistivity (ρ) of a Yb-based Kondo lattice, YbPd₂Si₂, which does not undergo magnetic ordering under ambient pressure condition. There are qualitative changes in the ρ(T) behavior due to the application of external pressure. While ρ is found to vary quadratically below 15K (down to 45mK) characteristic of Fermi-liquids, a drop is observed below 0.5K for P
