Abstract

In situ high-pressure (HP) and high-temperature (HT) energy dispersive X-ray diffraction of shandite-phase Co_3-x- Fe_xSn₂S₂ was carried out in the pressure range of 0-11 GPa and temperature range from room temperature to 1673 K. The Fe solubility limit x_max rises from below 0.6 up to 1.0 following HP and HT heat treatments. The ferromagnetic transition temperatures (T_C) of Co_3-xFe_xSn₂S₂ decreases with x, and T_C changes from 175(5)K (x = 0) to 68(3)K (x = 1), and this result is in qualitative agreement with theoretical calculations using the density functional theory with a pseudopotential. These results indicate that HP and HT techniques enable us to expand the solubility limits and magnetic phase diagrams in sulfides.
