An electron-paramagnetic-resonance study of the iron pyrite crystals grown by the method of chemical-vapor transport is reported. Cr3+ and Ni2+ ions were detected as substitutional impurities. An effective spin S =1/2 defect species that exhibits hyperfine couplings to the two natural isotopes of chlorine was detected in sulfur-deficient FeS2 grown by using ICl3 as a transport agent. This species can be identified as the defect species (SCl)2-. The similarity and differences exhibited by this defect species in the sulfur-deficient Fe pyrite and the chalcogen-deficient Ru pyrites are discussed.
