    Compressibility systematics of calcite-type borates : An experimental and theoretical structural study on ABO3 (A = Al, Sc, Fe and In) 
    Santamaría Pérez, David; Gomis Hilario, Oscar; Sans, Juan Ángel; Ortiz, H. M.; Vegas, Ángel; Errandonea, Daniel; Ruiz-Fuertes, Javier; Martínez-García, Domingo; García-Domene, B.; Pereira, ALJ; Manjón Herrera, Francisco Javier; Rodríguez-Hernández, Placida; Muñoz, A.; Piccinelli, F.; Bettinelli, M.; Popescu, C. (American Chemical Society, 2014-02-27)
    The structural properties of calcite-type orthoborates ABO(3) (A = Al, Fe, Sc, and In) have been investigated at high pressures up to 32 GPa. They were studied experimentally using synchrotron powder X-ray diffraction and ...
