Superorders and acoustic modes folding in BiFeO/LaFeO superlattices
R. Gu, R. Xu, F. Delodovici +18
Superlattices are materials created by the alternating growth of two chemically different materials. The direct consequence of creating a superlattice is the folding of the Brillou…
Anisotropy in the dielectric function of BiTe from first principles: From the UV-visible to the infrared range
R. Busselez, A. Levchuk, P. Ruello +2
The dielectric properties of BiTe, a layered compound crystallizing in a rhombohedral structure, are investigated by means of first-principles calculations at the random ph…
Non-thermal transport of energy driven by photoexcited carriers in switchable solid states of GeTe
R. Gu, T. Perrault, V. Juvé +10
Phase change alloys have seen widespread use from rewritable optical discs to the present day interest in their use in emerging neuromorphic computing architectures. In spite of th…
Ultrafast light-induced shear strain probed by time-resolved X-ray diffraction: the model multiferroic BiFeO as a case study
V. Juvé, R. Gu, S. Gable +12
Enabling the light-control of complex systems on ultra-short timescales gives rise to rich physics with promising applications. While crucial, the quantitative determination of bot…
On the magnetoelastic and magnetoelectric couplings across the antiferromagnetic transition in multiferroic BiFeO3
Mariusz Lejman, Charles Paillard, Vincent Juvé +7
Clear anomalies in the lattice thermal expansion (deviation from linear variation) and elastic properties (softening of the sound velocity) at the antiferromagnetic-to-paramagnetic…
Advances in applications of time-domain Brillouin scattering for nanoscale imaging
Vitalyi E. Gusev, Pascal Ruello
Time-domain Brillouin scattering is an all-optical experimental technique based on ultrafast lasers applied for generation and detection of coherent acoustic pulses on time duratio…
