AΛ-shaped change in the thermomagnetic curve in iron sulfide FeS_<1-10> (Y-transformation) was investigated experimentally. It was found that the height of peak was increased by decreasing the heating speed of the specimen. Temperature hysteresis in the thermomagnetic curves were also found at the low temperature side of the peak. Excess specific heat corresponding to the thermomagnetic anomaly was observed; the amount of anomalous heat absorption during the transformation was of the order of 100 cal/mol. It was concluded that the change of magnetism at the transformation is due to the ferrimagnetic distribution of ferrous and ferric ions and the change of vacant site distribution at the transformation.
