By combining the shock compression technique together with X-ray diffraction (XRD) and velocity interferometer (VISAR), the structural phase changes along their Hugoniot of (Mg,Fe)O and FeO under high pressure and temperature were probed up to 270 GPa. The solid-liquid boundary of FeO and the B1-B2 phase transition of (Mg,Fe)O could be observed. These conditions could occur in super-Earths with deeper core-mantle boundaries and the phase transition could influence the rheological properties of the mantle.<eng> Open Access Urheberrechtsschutz 1.0 vorgelegt von Khachiwan Buakor GutachterInnen: Thomas Tschentscher (European XFEL) ; Carmen Sanchez-Valle (Universität Münster, Institut für Mineralogie) ; Hauke Marquardt (University of Oxford, Department of Earth Sciences) Dissertation Universität Rostock 2025 530 https://purl.uni-rostock.de/rosdok/id00005270 Dynamic compression experiments of (Mg,Fe)O at X-ray free electron laser and large laser facilities--(DE-627)196785274X urn:nbn:de:gbv:28-rosdok_id00005270-9 doi: 10.18453/rosdok_id00005270 oclc: 1582442255 ppn: (DE-627)1967852448
