Pressure effect on the transport properties in heavy-fermion semimetal CeRu4Sb12

We have investigated the effect of pressure on the transport properties in the heavy-fermion semimetal CeRu4Sb12. A characteristic temperature Tm, below which the electrical resistivity ρ(T) shows a steep decrease, is found to increase with hydrostatic pressure (Ph). Non-Fermi liquid (NFL) behavior in ρ is suppressed with an extension of Fermi-liquid regime under Ph even in the absence of a magnetic field. Under the uniaxial pressure, considerable change of NFL behavior is observed in the presence of magnetic fields
