“…Having determined the sample geometry by static XRD and ellipsometry measurements, we adjust the simulated dynamics via the sound velocity in LSMO and LAO, respectively, to the experimental data. The result agrees well with values reported by other groups 35,36 . For comparison, a similar experiment reported earlier by our group gave 20% higher sound velocities due to insufficient temporal and angular resolution of our XRD setup 18 .…”

A benchmark experiment is reported that demonstrates the shortening of hard X‐ray pulses in a synchrotron‐based optical pump–X‐ray probe measurement. The pulse‐shortening device is a photoacoustic Bragg switch that reduces the temporal resolution of an incident X‐ray pulse to approximately 7.5 ps. The Bragg switch is employed to monitor propagating sound waves in nanometer thin epitaxial films. From the experimental data, the pulse duration, diffraction efficiency and switching contrast of the device can be inferred. A detailed efficiency analysis shows that the switch can deliver up to 109 photons s−1 in high‐repetition‐rate synchrotron experiments.

“…The electronic and magnetic properties have been carefully studied in many manganites; in particular, there is a wealth of information on La 1−x Sr x MnO 3 since high quality single crystals of this family are available. The lattice properties remain weakly investigated, and the data published so far again refer mainly to the La-Sr compounds [4][5][6][7][8][9][10][11]. It has been revealed that the longitudinal sound velocity in La 1−x Sr x MnO 3 single crystals essentially depends on temperature, the increase of Sr content results in a decrease of this dependence.…”
