Stability of the tetragonal phase of BaZrO3 under high pressure
Constance Toulouse, Danila Amoroso, Robert Oliva +8
In this paper, we revisit the high-pressure behavior of BaZrO3 by a combination of first-principle calculations, Raman spectroscopy, and x-ray diffraction under high pressure. We c…
Patterning enhanced tetragonality in BiFeO3 thin films with effective negative pressure by helium implantation
C. Toulouse, J. Fischer, S. Farokhipoor +13
Helium implantation in epitaxial thin films is a way to control the out-of-plane deformation independently from the in-plane strain controlled by epitaxy. In particular, implantati…
Role of the ferroelastic strain in the optical absorption of BiVO4
Christina Hill, Mads C. Weber, Jannis Lehmann +4
Bismuth vanadate (BiVO4) has recently been under focus for its potential use in photocatalysis thanks to its well-suited absorption edge in the visible light range. Here, we charac…
Imaging of Strain Driven Magnetic Domains and Strong Spin-Phonon Coupling in Epitaxial Thin Films of SrRuO3
Shekhar Tyagi, V. G. Sathe, Gaurav Sharma +3
Epitaxial thin films of SrRuO3 with large strain disorder were grown using pulsed laser deposition method which showed two distinct transition temperatures in Magnetic measurements…
Lattice dynamics and Raman spectrum of BaZrO3 single crystals
Constance Toulouse, Danila Amoroso, Cong Xin +7
BaZrO3 is a perovskite that remains in the simple cubic phase at all temperatures, hence with no first-order Raman-active phonon mode allowed by symmetry. Yet, it exhibits an inten…
Temperature-dependent photo-response in multiferroic BiFeO revealed by transmission measurements
F. Meggle, M. Viret, J. Kreisel +1
We studied the light-induced effects in BiFeO single crystals as a function of temperature by means of optical spectroscopy. Here we report the observation of several light-ind…
