摘要

We have measured the resistance of CeRu3.5Si2 under pressures up to 18 kbar down to 1 K. The extra Ru was introduced to stabilize the desired CeRu3Si2 phase. Under pressure, the resistance of CeRu3Si2 varies as R(T) = R0 + αT2 at low temperature and both R0 and α change drastically. The residual resistance R0 decreases rapidly but linearly with pressure increase. On the other hand, the superconducting transition temperature Tc increases with pressure at a rate of 3.7 × 10-5 K bar-1. These observations can be explained consistently in terms of a 4f-density of states reduction under pressure.
