A study was made of the composition dependence of the Mössbauer effect in the FeS1+x system in the range 0 ≪ x ≪ 0.135 at room temperature. The observed changes of the Mössbauer parameters are attributed to phase transitions and related to the variation of the concentration of iron vacancies with composition. The measured value of the quadrupole splitting is in good agreement with the prediction from the point charge model. The presence of Fe3+ could not be inferred from any observation in the studied range of concentration. The observed influence of iron vacancies indicates a strong superexchange which can be held responsible for the ferromagnetic bond of iron spins in the C‐plane. A short range order of vacancies is suggested for the explanation of the observed composition dependence of the phase transitions.
