　BiFeO₃ (BFO) has coexisting ferroelectric and magnetic order at 300 K and electromagnon modes that can shed light on the coupling between them. Our goal was to use intense THz pulses to pump these modes and probe the resulting lattice displacements with time-resolved XRD to obtain microscopic insight into the relationship between structural dynamics and photoinduced polarization changes in BFO.
