Phase 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...
متن کاملHigh-pressure / High-temperature Synthesis of Transition Metal Oxide Perovskites
Perovskite and related Ruddlesden-Popper type transition metal oxides synthesised at high pressures and temperatures during the last decade are reviewed. More than 60 such new materials have been reported since 1995. Important developments have included perovskites with complex cation orderings on A and B sites, multiferroic bismuth-based perovskites, and new manganites showing colossal magneto...
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 کاملPressure-driven insulator-metal transition in cubic phase UO2
Understanding the electronic properties of actinide oxides under pressure poses a great challenge for experimental and theoretical studies. Here, we investigate the electronic structure of cubic phase uranium dioxide at different volumes using a combination of density functional theory and dynamical mean-field theory. The ab initio calculations predict an orbital-selective insulator-metal trans...
