Full spatiotemporal control of laser-excited periodic surface deformations
J. -E. Pudell, M. Sander, R. Bauer +3
We demonstrate full control of acoustic and thermal periodic deformations at solid surfaces down to sub-nanosecond time scales and few-micrometer length scales via independent vari…

Time-resolved X-ray diffraction study of the structural dynamics in a ferroelectric thin film induced by sub-coercive fields
C. Kwamen, M. Rössle, W. Leitenberger +2
The electric field-dependence of structural dynamics in a tetragonal ferroelectric lead zirconate titanate thin film is investigated under sub-coercive and above-coercive fields us…

Ultrafast negative thermal expansion driven by spin-disorder
J. Pudell, A. von Reppert, D. Schick +5
We measure the transient strain profile in a nanoscale multilayer system composed of Yttrium, Holmium and Niobium after laser excitation using ultrafast X-ray diffraction. The stra…
