Description
The high-pressure and high-temperature structural behavior of FeP2 is investigated by means of synchrotron x-ray powder diffraction combined with a laser heating technique up to 70 GPa and at least 1800 K. No phase transition of FeP2 occurs up to 68 GPa at room temperature. While a new phase of FeP2 assigned to the CuAl2-type structure (I4/mcm, Z = 4) is observed at 70 GPa after laser-heating. This new phase presents a quenchable property on decompression to ambient conditions. Our results update previous experimental data and are consistent with theoretical studies. (authors)
