Using a clamp-type sintered diamond-tipped opposed anvil apparatus, we have carried out electrical resistance measurements of (SN)/sub x/ from 2.3 to 300 K at various pressures up to 400 kbar. We found that the normal conductivity of (SN)/sub x/ increased rapidly at low pressures and saturated around 50 to 70 kbar. Further application of pressure resulted in a monotonic decrease in conductivity up to 400 kbar. We also observed the onset of a superconducting transition in (SN)/sub x/ at temperatures from 2 to 3 K and pressures from 130 to 400 kbar. The onset temperatures are considerably higher than at atmospheric pressure and increase further with increasing pressure.
