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…
Phase segregation in MgZnO probed by optical absorption and photoluminescence at high pressure
V. Marín-Borrás, J. Ruiz-Fuertes, A. Segura. +1
The appearance of segregated wurtzite MgZnO with low Mg content in thin films with affected by phase separation, cannot be reliably probed with crystallographic…
Ambient temperature high-pressure-induced ferroelectric phase transition in CaMnTiO
J. Ruiz-Fuertes, T. Bernert, D. Zimmer +7
The ferroelectric to paraelectric phase transition of multiferroic CaMnTiO has been investigated at high pressures and ambient temperature by second harmonic generation (SH…
Pressure impact on the stability and distortion of the crystal structure of CeScO3
Daniel Errandonea, David Santamaria-Perez, Domingo Martinez-Garcia +5
The effects of high pressure on the crystal structure of orthorhombic (Pnma) perovskite type cerium scandate have been studied in situ under high pressure by means of synchrotron x…
First-Principles Study of InVO4 under Pressure: Phase Transitions from CrVO4- to AgMnO4-Type Structure
Sinhué López-Moreno, Plácida Rodríguez-Hernández, Alfonso Muñoz +1
First-principles calculations have been carried out to study the InVO4 compound under pressure. In this work, total energy calculations were performed in order to analyze the struc…
High-pressure structural, elastic, and thermodynamic properties of zircon-type HoPO4 and TmPO4
O. Gomis, B. Lavina, P. Rodríguez-Hernández +4
Zircon-type HoPO4 and TmPO4 have been studied by single-crystal x-ray diffraction and ab initio calculations. We report information on the influence of pressure on the crystal stru…
