Nanolayer-Confined Strain Waves in Femtosecond-Optical-Vortex-Excited Multiferroic BiFeO3.
Strain waves provide a route to reshape nanoscale order in functional materials, where lattice deformation couples to charge and spin degrees of freedom. Real-space tracking of these transient strain fields is critical for connecting acoustic excitation to functionality, yet progress has been limited because buried cry...
