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…
A combined high-pressure experimental and theoretical study of the electronic band-structure of scheelite-type AWO4 (A = Ca, Sr, Ba, Pb) compounds
R. Lacomba-Perales, D. Errandonea, A. Segura +6
The optical-absorption edge of single crystals of CaWO4, SrWO4, BaWO4, and PbWO4 has been measured under high pressure up to ~20 GPa at room temperature. From the measurements we h…
High-pressure structural phase transitions in CuWO4
J. Ruiz-Fuertes, D. Errandonea, R. Lacomba-Perales +9
We study the effects of pressure on the structural, vibrational, and magnetic behavior of cuproscheelite. We performed powder x-ray diffraction and Raman spectroscopy experiments u…
High-pressure phase transitions and compressibility of wolframite-type tungstates
J. Ruiz-Fuertes, S. Lopez-Moreno, D. Errandonea +7
This paper reports an investigation on the phase diagram and compressibility of wolframite-type tungstates by means of x-ray powder diffraction and absorption in a diamond-anvil ce…
High-pressure structural investigation of several zircon-type orthovanadates
D. Errandonea, R. Lacomba-Perales, J. Ruiz-Fuertes +3
Room temperature angle-dispersive x-ray diffraction measurements on zircon-type EuVO4, LuVO4, and ScVO4 were performed up to 27 GPa. In the three compounds we found evidence of a p…
Optical absorption of divalent metal tungstates: Correlation between the band-gap energy and the cation ionic radius
R. Lacomba-Perales, J. Ruiz-Fuertes, D. Errandonea +2
We have carried out optical-absorption and reflectance measurements at room temperature in single crystals of AWO4 tungstates (A = Ba, Ca, Cd, Cu, Pb, Sr, and Zn). From the experim…
