Abstract Electrical properties of stoichiometric iron sulfide (FeS) are investigated under high pressure with a designed diamond anvil cell. The process of phase transition is reflected by changing the electrical conductivity under high pressure, and the conductivity of FeS with the NiAs structure is found to be much smaller than other phases. Two new phase transitions without structural change are observed at 34.7GPa and 61.3GPa. The temperature dependence of the conductivity is found to be similar to that of a semiconductor when the pressure is higher than 35GPa
