This multi-purpose instrument is optimized for electron- and ion-spectroscopy, imaging and pump–probe experiments at free-electron lasers [...] OpenAccess: PDF PDF (PDFA); 2018-07-2308:54 [PUBDB-2018-02650] Journal Article et al Elastic Softening of $\mathrm{(Mg_{0.8}Fe_{0.2})O}$ Ferropericlase Across the Iron Spin Crossover Measured at Seismic Frequencies Geophysical research letters 45(14), 6862 - 6868 (2018) [10.1029/2018GL077982]   We experimentally determined the bulk modulus of (Mg$_{0.8}$Fe$_{0.2}$)O ferropericlase across theiron spin transition and in the low-spin phase by employing a new experimental approach. In ourmeasurements, we simulate the propagation of a compressional seismic wave (P wave) through our sampleby employing a piezo-driven dynamic diamond anvil cell that allows to oscillate pressure at seismicfrequencies.
