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…

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…
