Disentangling charge and structural contributions during coherent atomic motions studied by ultrafast resonant x-ray diffraction
L. Rettig, A. Caviezel, S. O. Mariager +20
We report on the ultrafast dynamics of charge order and structural response during the photoinduced suppression of charge and orbital order in a mixed-valence manganite. Employing…
Watching the birth of a charge density wave order: diffraction study on nanometer-and picosecond-scales
C. Laulhé, T. Huber, G. Lantz +18
Femtosecond time-resolved X-ray diffraction is used to study a photo-induced phase transition between two charge density wave (CDW) states in 1T-TaS, namely the nearly commensu…
Ultrafast x-ray diffraction of a ferroelectric soft mode driven by broadband terahertz pulses
S. Grübel, J. A. Johnson, P. Beaud +14
Intense, few-cycle pulses in the terahertz frequency range have strong potential for schemes of control over vibrational modes in solid-state materials in the electronic ground-sta…
Ultrafast structural dynamics of the Fe-pnictide parent compound BaFe2As2
L. Rettig, S. O. Mariager, A. Ferrer +8
Using femtosecond time-resolved x-ray diffraction we investigate the structural dynamics of the coherently excited A1g phonon mode in the Fe-pnictide parent compound BaFe2As2. The…
Structural and Magnetic Dynamics in the Magnetic Shape Memory Alloy NiMnGa
S. O. Mariager, C. Dornes, J. A. Johnson +11
Magnetic shape memory Heusler alloys are multiferroics stabilized by the correlations between electronic, magnetic and structural order. To study these correlations we use time res…
Nonlinear lattice dynamics as a basis for enhanced superconductivity in YBa2Cu3O6.5
R. Mankowsky, A. Subedi, M. Först +13
THz-frequency optical pulses can resonantly drive selected vibrational modes in solids and deform their crystal structure. In complex oxides, this method has been used to melt elec…
