Physical Properties of SmS Metallic Phase at low temperature
The resistivity of SmS single crystal has been measured under pressure up to 8 GPa. As an applied pressure is increased, the electrical resistivity changes drastically. In particular it shows a kink at T<SUB>M</SUB> in the p vs T curve above 2 GPa. We found that the electrical resistivity shows the ρ=ρ<SUB>0</SUB>+AT<SUB>2</SUB> dependencewith a largecoefficient Abelow T<SUB>M</SUB>. If we ascribe this term to the electron-electron scattering, the electron correlation effect plays a dominant role in the high pressure region, which may correspond to the large γ value.
