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…
Localized excited charge carriers generate ultrafast inhomogeneous strain in the multiferroic BiFeO
D. Schick, M. Herzog, H. Wen +7
We apply ultrafast X-ray diffraction with femtosecond temporal resolution to monitor the lattice dynamics in a thin film of multiferroic BiFeO after above-bandgap photoexcitati…
Magneto-Optical Functions at the 3p resonances of Fe, Co, and Ni: Ab-initio description and experiment
F. Willems, S. Sharma, C. v. Korff Schmising +7
We present theoretical and experimental data on the magneto-optical contributions to the complex refractive index in the extreme ultraviolet (XUV) range covering the 3p resonances…
Thermoelastic study of nanolayered structures using time-resolved x-ray diffraction at high repetition rate
H. A. Navirian, D. Schick, P. Gaal +3
We investigate the thermoelastic response of a nanolayered sample composed of a metallic SrRuO3 (SRO) electrode sandwiched between a ferroelectric Pb(Zr0.2Ti0.8)O3 (PZT) film with…
Optical Writing of Magnetic Properties by Remanent Photostriction
V. Iurchuk, D. Schick, J. Bran +13
We present an optically induced remanent photostriction in BiFeO3, resulting from the photovoltaic effect, which is used to modify the ferromagnetism of Ni film in a hybrid BiFeO3/…
Following Strain-Induced Mosaicity Changes of Ferroelectric Thin Films by Ultrafast Reciprocal Space Mapping
D. Schick, A. Bojahr, M. Herzog +3
We investigate coherent phonon propagation in a thin film of ferroelectric PbZr0.2Ti0.8O3 (PZT) by ultrafast x-ray diffraction (UXRD) experiments, which are analyzed as time-resolv…
