Orbital fluctuations and spin-orbital-lattice coupling in Bi2Fe4O9
Aditya Prasad Roy, M. K. Chattopadhyay, Ranjan Mittal +4
Magnetic frustrations and degeneracies profoundly affect ground-state magnetic properties emerging from competing exchange interactions. Controlling such frustrations using orbital…
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…
Inelastic Neutron Scattering Studies of Phonon Spectra and Simulations in Tungstates, AWO4 (A = Ba, Sr, Ca and Pb)
Prabhatasree Goel, M. K. Gupta, R. Mittal +4
Lattice dynamics and high pressure phase transitions in AWO4 (A = Ba, Sr, Ca and Pb) have been investigated using inelastic neutron scattering experiments, ab-initio density functi…
High-Temperature Phonon Spectra of Multiferroic BiFeO3 from Inelastic Neutron Spectroscopy
M. Zbiri, H. Schober, N. Choudhury +5
We report inelastic neutron scattering measurements of the phonon spectra in a pure powder sample of the multiferroic material BiFeO3. A high-temperature range was covered to unrav…
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…
