Abstract
A new type of spin 1/2 chlorine-associated defect species has been observed by ESR in as-grown, sulfur-deficient FeS2 crystals grown by the method of chemical vapor transport using ICl3 as the transport agent. The ESR spectrum of this defect species exhibits a low symmetry and a weak hyperfine interaction with a single chlorine nucleus. The g-factor anisotropy indicates that this species is most likely a hole species, having a p5 electron configuration and localized at a sulfur atom. We assign this defect species as an (SCl)2- impurity defect, replacing (S-S)2- and locally associated with a Fe2+ vacancy created probably to compensate for the substitutional Cr3+ impurities.
