Anharmonic lattice vibrations play pivotal roles in the thermal dynamics in condense matters
and affect how the atoms interact and conduct heat. An in-depth understanding of the …

Ultrashort light pulses induce rapid deformations of crystalline lattices. In ferroelectrics,
lattice deformations couple directly to the polarization, which opens the perspective to …

A data-driven framework is presented for building magneto-elastic machine-learning
interatomic potentials (ML-IAPs) for large-scale spin-lattice dynamics simulations. The …

The ultrafast switching of magnetization in multiferroic materials by a femtosecond laser
could provide various advantages in photonics and magnonics. An efficient approach to …

Enabling the light control of complex systems on ultrashort timescales gives rise to rich
physics with promising applications. Although crucial, the quantitative determination of both …

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 Brillouin …

Two-dimensional multiferroic (2D) materials have garnered significant attention due to their
potential in high-density, low-power multistate storage and spintronics applications …

We report results from a study of the crystal and magnetic structures of strontium-doped
BiFeO 3 using neutron powder diffraction and the Rietveld method. Measurements were …

We performed Brillouin light scattering spectroscopy on a single crystal of BiFeO 3 (BFO) in
the temperature range from 110 to 300 K and observed the Brillouin scattering from the LA …
