An effective magnetic field from optically driven phonons
Published 2016“…This nonlinear mode mixing drives rotations as well as displacements of the crystal-field atoms, mimicking the application of a magnetic field and resulting in the excitation of spin precession in the rare-earth orthoferrite ErFeO 3. Coherent control of lattice rotations may become applicable to other interesting problems in materials research-for example, as a way to affect the topology of electronic phases.…”
