Impact of the surface phase transition on magnon and phonon excitations in BiFeO3 nanoparticles
Ian Aupiais, Pierre Hemme, Marc Allen +8
We have performed Raman scattering measurements on BiFeO3 nanoparticles and studied both magnetic and lattice modes. We reveal strong anomalies between 140 K and 200 K in the frequ…
Colossal electromagnon excitation in the non-cycloidal phase of TbMnO3 under pressure
Ian Aupiais, Masahito Mochizuki, Hideaki Sakata +4
The magnetoelectric coupling, i.e., cross-correlation between electric and magnetic orders, is a very desirable property to combine functionalities of materials for next-generation…
Size-dependent bistability in multiferroic nanoparticles
Marc Allen, Ian Aupiais, Maximilien Cazayous +1
Most multiferroic materials with coexisting ferroelectric and magnetic order exhibit cycloidal antiferromagnetism with wavelength of several nanometers. The prototypical example is…
