Author(s): Héloïse Damas, Carl S. Davies, Petr M. Vetoshko, Vladimir I. Belotelov, Andrzej Stupakiewicz, and Andrei Kirilyuk Midinfrared laser pulses tuned to optical phonon frequencies can induce magnetization switching in magnetic dielectrics, but the underlying mechanisms remain unclear, since excitations of the crystal lattice can simultaneously produce heating and nonthermal strain. Here, we study the response of lab… [Phys. Rev. Lett. 137, 036704] Published Thu Jul 16, 2026
