Ultrafast coupling between light, coherent lattice vibrations, and the magnetic structure of semicovalent LaMnO(3).
Coherent lattice vibrations are excited and probed with pulses of 10 fs duration in LaMnO(3). The measured frequencies correspond to those of Jahn-Teller stretching and of out-of phase rotations of the oxygen octahedra. Surprisingly, the amplitude and damping rate of both modes exhibit a sharp disco...
