    Crystal Chemistry of CdIn2S4, MgIn2S4, and MnIn2S4 thiospinels under high pressure 
    Santamaría Pérez, David; Amboage, Mónica; Manjón Herrera, Francisco Javier; Errandonea, Daniel; Muñoz, Alfonso; Rodríguez Hernández, Plácida; Mújica, Andrés; Radescu, Silvana; Ursaki, Veacheslav; Tinginyanu, Ivan (American Chemical Society, 2012-07-05)
    We report X-ray diffraction measurements in CdIn2S4, MgIn2S4, and MnIn2S4 thiospinels at room temperature and high pressures. The pressure dependences of the structural parameters have been determined and compared to those ...

    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 ...

    Lattice dynamics study of HgGa2Se4 at high pressures 
    Vilaplana Cerda, Rosario Isabel; Gomis Hilario, Oscar; Manjón Herrera, Francisco Javier; Ortiz, H. M.; Pérez González, E.; López Solano, Javier; Rodríguez Hernández, Plácida; Múñoz, Alfonso; Errandonea, Daniel; Ursaki, V.; Tiginyanu, Ivan (American Chemical Society, 2013-08)
    We report on Raman scattering measurements in mercury digallium selenide (HgGa2Se4) up to 25 GPa. We also performed, for the low-pressure defect-chalcopyrite structure, lattice-dynamics ab initio calculations at high ...

    Structural and vibrational study of pseudocubic CdIn2Se4 under compression 
    Santamaría Pérez, David; Gomis, O.; Pereira, A. L. J.; Vilaplana Cerda, Rosario Isabel; Popescu, Catalin; Sans Tresserras, Juan Ángel; Manjón Herrera, Francisco Javier; Rodríguez Hernández, Plácida; Muñoz, Alfonso; Ursaki, Vladislav V.; Tiginyanu, Ion M. (American Chemical Society, 2014-11-20)
    We report a comprehensive experimental and theoretical study of the structural and vibrational properties of a-CdIn2Se4 under compression. Angle-dispersive synchrotron X-ray diffraction and Raman spectroscopy evidence that ...

    Vibrational properties of CdGa2S4 at high pressure 
    Gallego-Parra, Samuel; Gomis, O.; Vilaplana Cerda, Rosario Isabel; Ortiz, H.M.; Perez-Gonzalez, E.; Luna Molina, Ramón; Rodríguez-Hernández, Plácida; MUÑOZ, ALFONSO; URSAKI, VEACHESLAV; TIGINYANU, IVAN; Manjón, Francisco-Javier (American Institute of Physics, 2019-03-21)
    [EN] Raman scattering measurements have been performed in cadmium digallium sulphide (CdGa2S4) with defect chalcopyrite structure up to 25 GPa in order to study its pressure-induced phase transitions. These measurements ...
