Driving magnetic order in a manganite by ultrafast lattice excitation
Physical Review B - Condensed Matter and Materials Physics 84:24 (2011)
Abstract:
Femtosecond midinfrared pulses are used to directly excite the lattice of the single-layer manganite La 0.5Sr 1.5MnO 4. Magnetic and orbital orders, as measured by femtosecond resonant soft x-ray diffraction with an x-ray free-electron laser, are reduced within a few picoseconds. This effect is interpreted as a displacive exchange quench, a prompt shift in the equilibrium value of the magnetic- and orbital-order parameters after the lattice has been distorted. Control of magnetism through ultrafast lattice excitation may be of use for high-speed optomagnetism. © 2011 American Physical Society.Monochromatised XUV pulses for ultrafast science at the artemis facility

Abstract:
XUV pulses produced through high harmonic generation can probe electron dynamics in complex solid materials and in gas-phase atoms and molecules. This is demonstrated in gas-phase and condensed matter experiments at the Artemis facility. © 2012 OSA.Ultrafast Tr-ARPES with artemis XUV beamline
