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…

Manifestation of nematic degrees of freedom in the Raman response function of iron pnictides
Una Karahasanovic, Florian Kretzschmar, Thomas Boehm +4
We establish a relation between the Raman response function in the channel and the electronic contribution to the nematic susceptibility within the spin-driven approach to…
