• Hardness and elasticity in cubic ruthenium dioxide 

      Leger, Jean Michel; Djemia, P.; Ganot, F.; Haines, Julian; Pereira, Altair Soria; Jornada, Joao Alziro Herz da (2001) [Artigo de periódico]
      The Knoop hardness of the highly incompressible cubic phase of ruthenium dioxide was found to be 19–20 GPa from indentation tests. This value scales well with the shear modulus approximated by the elastic constant C44 of ...
    • Ultrastable phonon frequencies in α-quartz-type BPO4 at high temperature 

      Le-Parc, Rozenn; Buixaderas, Elena; Levelut, Claire; Hermet, Patrick; Pereira, Altair Soria; Cambon, Olivier; Roiland, Claire; Simon, Patrick; Haines, Julian (2019) [Artigo de periódico]
      The Raman modes of α-quartz-type boron phosphate were found to be extremely stable in frequency over a large temperature range from 300–1000 K. In order to determine the origin of this behavior, the material was also studied ...
