Magnetic transitions in CaMn7O12 : a Raman observation of spin-phonon couplings
C. Toulouse, C. Martin, M-A. Measson +3
The quadruple Calcium manganite (CaMn7O12) is a multiferroic material that exhibits a giant magnetically-induced ferroelectric polarization which makes it very interesting for magn…
Strain and Magnetic Field Induced Spin-Structure Transitions in Multiferroic BiFeO3
A. Agbelele, D. Sando, C. Toulouse +17
The magnetic-field-dependent spin ordering of strained BiFeO3 films is determined using nuclear resonant scattering and Raman spectroscopy. The critical field required to destroy t…
Temperature evolution of the band-gap in BiFeO3 traced by resonant Raman scattering
Mads Christof Weber, Mael Guennou, Constance Toulouse +4
Knowledge of the electronic band structure of multiferroic oxides, crucial for the understanding and tuning of photo-induced effects, remains very limited even in the model and tho…
Driving spin excitations by hydrostatic pressure in BiFeO3
J. Buhot, C. Toulouse, Y. Gallais +10
Optical spectroscopy has been combined with computational and theoretical techniques to show how the spin dynamics in the model multiferroic BiFeO3 responds to the application of h…
Phonons in the multiferroic langasite BaNbFeSiO : evidences for symmetry breaking
C Toulouse, M Cazayous, S De Brion +7
The chiral langasite BaNbFeSiO is a multiferroic compound. While its magnetic order below T=27 K is now well characterised, its polar order is still con…
Lattice and spin excitations in multiferroic h-YMnO3
C. Toulouse, L. Chaix, J. Liu +11
We used Raman and terahertz spectroscopies to investigate lattice and magnetic excitations and their cross-coupling in the hexagonal YMnO3 multiferroic. Two phonon modes are strong…
Lattice and spin excitations in multiferroic h-YbMnO3
J. Liu, C. Toulouse, P. Rovillain +6
Lattice and spin excitations have been studied by Raman scattering in hexagonal YbMnO3 single crystals. The temperature dependences of the phonon modes show that the E2 mode at 256…
