    • openAccess   Field enhanced bulk conductivity of acceptor-doped BaTi1−xCaxO3−x ceramics 

      Masó, Nahum; Prades Tena, Marta; Beltrán Mir, Héctor; Cordoncillo, Eloisa; Sinclair, Derek C.; West, Anthony R. American Institute of Physics (2010)
      The electrical properties of Ca-doped BaTiO3 are very different when Ca substitutes onto Ba or Ti sites. The p-type semiconductivity of Ti-substituted ceramics increases reversibly by one to two orders of magnitude under ...

    • openAccess   High-pressure study of the behavior of mineral barite by x-ray diffraction 

      Santamaría Pérez, D.; Gracia, Lourdes; Garbarino, G.; Beltran, Armando; Chulia-Jordan, Raquel; Gomis Hilario, Óscar; Errandonea, Daniel; Ferrer Roca, Chantal María; Martínez García, Domingo; Segura García del Río, Alfredo American Physical Society (2011-08-02)
      In this paper, we report the angle-dispersive x-ray diffraction data of barite, BaSO4 , measured in a diamond-anvil cell up to a pressure of 48 GPa, using three different fluid pressure-transmitting media (methanol-ethanol ...
