    High-pressure lattice dynamical study of bulk and nanocrystalline In2O3 
    Garcia Domene, Braulio; Ortiz, H. M.; Gomis Hilario, Oscar; Sans, J. A.; Manjón Herrera, Francisco Javier; Muñoz, A.; Rodríguez-Hernández, P.; Achary, S. N.; Errandonea, D.; Martínez-García, D.; Romero, A. H.; Singhal, A.; Tyagi, A. K. (American Institute of Physics (AIP), 2012-12-19)
    The effect of pressure on the vibrational properties of bulk and nanocrystallinepowders of cubic bixbyite-type In2O3 has been investigated at room temperature by means of Raman spectroscopy up to 31.6 and 30¿GPa, respectively. ...

    New high-pressure phase and equation of state of Ce2Zr2O8 
    Errandonea, Daniel; Kumar, R.S.; Achary, S.N.; Gomis Hilario, Oscar; Manjón Herrera, Francisco Javier; Shukla, R.; Tyagi, A.K. (American Institute of Physics (AIP), 2012-03-08)
    In this paper we report a new high-pressure rhombohedral phase of Ce2Zr2O8 observed in high-pressure angle-dispersive x-ray diffraction and Raman spectroscopy studies up to nearly 12 GPa. The ambient-pressure cubic phase ...
