【 摘 要 】

Detailed pressure-temperature phase diagrams of heavy lanthanide sesquisulfides Ln(2)S(3) (Ln = Yb and Lu) have been investigated by in-situ x-ray diffraction experiments under high pressure and high temperature using synchrotron radiation and multi-anvil press. Based on the results of the in-situ observation, the single gamma-phase (Th3P4-type structure, I (4) over bar 3d) samples of Ln(2)S(3) (Ln = Yb and Lu) have been synthesized under high pressure. The physical properties of the compounds were studied by electrical resistivity, specific heat, and magnetic susceptibility measurements between 2 K and 300 K. (C) 2017 Elsevier B.V.
