  • The electrical properties of stoichiometric iron sulfide (FeS) were investigated under high pressure with a designed diamond anvil cell (DAC). The process of phase transition was reflected on the discontinuity of electrical conductivity changing with high pressure. The conductivity of FeS with NiAs structure was found to be much smaller than other phases. Two new phase transitions without structural change were observed at 34.7 GPa and 61.3 GPa.
