    Effect of pressure on La-2(WO4)(3) with a modulated scheelite-type structure 
    Sabalisck, N.P.; Lopez Solano, Javier; Guzmán-Afonso, C.; Santamaría Pérez, David; González-Silgo, C.; Mújica, Andrés; Muñoz, Alfonso; Rodríguez Hernández, Plácida; Radescu, Silvana; Vendrell, X.; Mestres, L.; Sans Tresserras, Juan Ángel; Manjón Herrera, Francisco Javier (American Physical Society, 2014-05-27)
    We have studied the effect of pressure on the structural and vibrational properties of lanthanum tritungstate La2(WO4)3. This compound crystallizes under ambient conditions in the modulated scheelite-type structure known ...

    Metastable structural transformations and pressure-induced amorphization in natural (Mg,Fe)2SiO4 olivine under static compression: A Raman spectroscopic study 
    Santamaría Pérez, David; Thomson, Andrew; Segura, Alfredo; Pellicer Torres, Julio; Manjón, Francisco-Javier; Cora, Furio; McColl, Kit; Wilson, Mark; Dobson, David; McMillan, Paul (Mineralogical Society of America, 2016-07)
    [EN] Raman spectroscopic data were obtained for (Mg,Fe)(2)SiO4 samples during compression to 57 GPa. Single crystals of San Carlos olivine compressed hydrostatically above 41 GPa showed appearance of a new "defect" peak ...

    Pressure effects on the vibrational properties of alpha-Bi2O3: an experimental and theoretical study 
    Pereira, A. L. J.; Gomis, O.; Sans, J. A.; Pellicer-Porres, J.; Manjón Herrera, Francisco Javier; Beltran, A.; Rodríguez-Hernández, Plácida; Muñoz, Alfonso (IOP Publishing: Hybrid Open Access, 2014-06)
    We report an experimental and theoretical high-pressure study of the vibrational properties of synthetic monoclinic bismuth oxide (alpha-Bi2O3), also known as mineral bismite. The comparison of Raman scattering measurements ...

    Pressure-induced amorphization of YVO4:Eu3+ nanoboxes 
    Ruiz Fuertes, Javier; Gomis, O.; León Luis, S. F.; Schrodt, N.; Manjón Herrera, Francisco Javier; Ray, Sudeshna; Santamaría Pérez, David; Sans Tresserras, Juan Ángel; Ortiz, H. M.; Errandonea, Daniel; Ferrer Roca, Chantal; Segura, A.; Martínez García, Domingo; Lavin, V.; Rodríguez Mendoza, U. R.; Muñoz, A. (IOP Publishing: Hybrid Open Access, 2016-01-15)
    A structural transformation from the zircon-type structure to an amorphous phase has been found in YVO4:Eu3+ nanoboxes at high pressures above 12.7 GPa by means of x-ray diffraction measurements. However, the pair distribution ...
