The high-pressure α/β phase transition in lead sulphide (PbS) X-ray powder diffraction and quantum mechanical calculations
The high-pressure behaviour of PbS was investigated by angular dispersive X-ray powder diffraction up to pressures of 6.8 GPa. Experiments were accompanied by first principles calculations at the density functional theory level. By combining both methods reliable data for the elastic properties of rock-salt type αand high-pressure β-PbS could be obtained. β-PbS could be determined to crystallis...
متن کاملHigh-pressure phase transition in Y3Fe5O12.
Yttrium iron garnet (YIG, Y3Fe5O12) was examined up to 74 GPa and 1800 K using synchrotron x-ray diffraction in a diamond anvil cell. At room temperature, YIG remained in the garnet phase until abrupt amorphization occurred at 51 GPa, consistent with earlier studies. Upon laser heating up to 1800 K, the material transformed to a single-phase orthorhombic GdFeO3-type perovskite of composition (Y...
متن کاملReversible high-pressure phase transition in LaN
In situ high-pressure X-ray powder diffraction experiments on LaN up to 60.1 GPa at ambient temperature in a diamond-anvil cell revealed a reversible, first-order structural phase transition starting at 22.8 GPa and completed at 26.5 GPa from the ambient cubic phase (Fm 3m, no. 225) to a tetragonal high-pressure phase (P4/nmm, no. 19, a1⁄4 4.1060(6), c1⁄4 3.0446(6) Å, Z1⁄4 2, wRp1⁄4 0.011), whi...

متن کاملPhase Transition in Mixed Transition Metal Oxides under High Pressure
Mixed crystals can be categorized as the crystal in which two or more different types of atoms are present and configured. These atoms interact each other in the influence of Coulomb force of attraction and the presence of short range repulsion force. Due to this interaction they tends to be arranged in equilibrium state and forms new material. A pure crystal can be doped by impurities with pro...
