Observation of electromagnon excitations in the BiFe0 spiral magnet
M. Cazayous, Y. Gallais, A. Sacuto +3
Recently, oxide multiferroics have attracted much attention due to their large magnetoelectric effect which allows the tuning of magnetic properties with electric field and vice ve…
Electric field effect on BiFeO single crystal investigated by Raman spectroscopy
M. Cazayous, D. Malka, D. Lebeugle +1
Micro-Raman spectroscopy has been used to study lattice dynamics associated with the ferroelectric domains of a BiFeO single crystal at low temperature. The phonon assignment s…
Infrared phonon dynamics of multiferroic BiFeO3 single crystal
R. P. S. M. Lobo, R. L. Moreira, D. Lebeugle +1
We discuss the first infrared reflectivity measurement on a BiFeO3 single crystal between 5 K and room temperature. The 9 predicted ab-plane E phonon modes are fully and unambiguou…
Very large spontaneous electric polarization in BiFeO3 single crystals at room temperature and its evolution under cycling fields
D. Lebeugle, D. Colson, A. Forget +1
Electric polarization loops are measured at room temperature on highly pure BiFeO3 single crystals synthesized by a flux growth method. Because the crystals have a high electrical…
Room temperature coexistence of large electric polarization and magnetic order in BiFeO3 single crystals
Delphine Lebeugle, Dorothee Colson, Anne Forget +4
From an experimental point of view, room temperature ferroelectricity in BiFeO3 is raising many questions. Electric measurements made a long time ago on solid-solutions of BiFeO3 w…
