متن کاملHigh-pressure Raman scattering study on zircon- to scheelite-type structural phase transitions of RCrO4
High-pressure Raman scattering experiments were performed on the zircon-type RCrO4 R=Nd, Dy compounds with the space group I41 /amd by using diamond anvil cell techniques at room temperature. These two compounds exhibit similar Raman behaviors. Pressure-induced structural phase transitions were observed at the onset of 1.3 and 4.1 GPa for R=Nd and Dy, respectively. Moreover, pressure-released R...
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 کاملZircon to scheelite phase transition induced by pressure and magnetism in TbCrO4
The scheelite form of the TbCrO4 oxide has been obtained by treating TbCrO4-zircon at 4 GPa and 823 K. X-ray and neutron diffraction data reveal that the high-pressure polymorph of TbCrO4 crystallizes with tetragonal symmetry space group I41 /a and lattice parameters a=5.036 74 10 Å and c=11.3734 4 Å. Although bisdisphenoids TbO8 and tetrahedra CrO4 are present in both scheelite and zircon poly...
