The high-pressure behavior of CaMoO4
V. Panchal, N. Garg, H. K. Poswal +4
We report a high-pressure study of tetragonal scheelite-type CaMoO4 up to 29 GPa. In order to characterize its high-pressure behavior, we have combined Raman and optical-absorption…
The electronic structure of zircon-type orthovanadates: Effects of high-pressure and cation substitution
V. Panchal, D. Errandonea, A. Segura +4
The electronic structure of four ternary-metal oxides containing isolated vanadate ions is studied. Zircon-type YVO4, YbVO4, LuVO4, and NdVO4 are investigated by high-pressure opti…
Zircon to monazite phase transition in CeVO4
V. Panchal, S. Lopez-Moreno, D. Santamaria-Perez +6
X-ray diffraction and Raman-scattering measurements on cerium vanadate have been performed up to 12 and 16 GPa, respectively. Experiments reveal that at 5.3 GPa the onset of a pres…
Low temperature Raman study of Ca3Co2O6
Vinod panchal, Smita Gohil, Shankar Ghosh
We present low temperature Raman measurements on Ca3Co2O6. Shell model lattice dynamics calculations were done to determine the vibrational pattern of the expected Raman modes. In…
Non-monotonic size dependence of the elastic modulus of nanocrystalline ZnO embedded in a nanocrystalline silver matrix
Vinod Panchal, Shankar Ghosh, Smita Gohil +2
We present the first high pressure Raman study on nanocrystalline ZnO films with different average crystallite sizes. The problem of low Raman signals from nano sized particles was…
Raman and x-ray diffraction investigations on BaMoO4 under high pressures
Vinod Panchal, Nandini Garg, Surinder M. Sharma
X-ray diffraction and Raman scattering studies on scheelite structured barium molybdate show that, at 5.8 GPa, it undergoes a first order phase transition to fergusonite structure…
