Nonlinear phononics in BiTe nanoscale thin films: A theoretical approach
A. Levchuk, R. Busselez, G. Vaudel +3
Density Functional Theory (DFT) calculations not only allow to predict the vibrational and optical properties of solids but also to understand and disentangle the mechanisms playin…
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…
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…
