Summary

Raman and reflection spectra of synthetic MS2 (M=Fe, Co, and Ni) crystals with the structure type pyrite have been measured under high pressure, up to about 130 kbar, at room temperature. Changes in the Raman frequency of Ag mode with pressure revealed the atomic displacement of sulfur atoms. From the reflectance measurements, changes in the electronic state depending on pressure were obtained. Results indicate that the electronic and magnetic properties of these materials can be interpreted on the basis of band schemes and also throw light on a problem of the stability of ore minerals having the pyrite structure.
