Pressure-induced phase transitions in AgClO4
D. Errandonea, L. Gracia, A. Beltran +2
AgClO4 has been studied under compression by x-ray diffraction and density functional theory calculations. Experimental evidence of a structural phase transition from the tetragona…
Compressibility and structural stability of ultra-incompressible bimetallic interstitial carbides and nitrides
D. Errandonea, J. Ruiz-Fuertes, J. A. Sans +4
We have investigated by means of high-pressure x-ray diffraction the structural stability of Pd2Mo3N, Ni2Mo3C0.52N0.48, Co3Mo3C0.62N0.38, and Fe3Mo3C. We have found that they remai…
Anomalous high-pressure Jahn-Teller behavior in CuWO4
J. Ruiz-Fuertes, A. Segura, F. Rodriguez +2
High-pressure optical-absorption measurements performed in CuWO4 up to 20 GPa provide experimental evidence of the persistence of the Jahn-Teller (JT) distortion in the whole press…
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…
In situ high-pressure synchrotron x-ray diffraction study of CeVO4 and TbVO4 up to 50 GPa
D. Errandonea, R. S. Kumar, S. N. Achary +1
Room temperature angle-dispersive x-ray diffraction measurements on zircon-type TbVO4 and CeVO4 were performed in a diamond-anvil cell up to 50 GPa using neon as pressure-transmitt…
