Engineering Band Structures in Correlated Oxides
The electronic structure of short period digital superlattices of two different phases depends strongly on the superlattice architecture. We have fabricated digital superlattices of super cells consisting of N layers of LaMnO3 and N layers of SrTiO 3, N=1, 2, 3, 8, and measured their optical …

Ultrafast Response of Photoexcited Carriers in Transition Metal Oxides under High Pressure
In this work, optical pump – near-infrared probe and near-infrared pump – mid-infrared probe spectroscopy are used for the investigation of pressure-induced insulator-to-metal transitions in transition metal oxide compounds. The materials under study are α-Fe₂O₃, also known as hematite, and VO₂. …

Crystal structure, electron density and chemical bonding in inorganic compounds studied by the Electric Field Gradient
… complex systems and finally tackling strongly correlated oxides. Simultaneously, the EFGs for the studied compounds were determined experimentally by NMR spectroscopists. This close collaboration enables the comparison of the calculated EFGs with the experimental observations, which makes it …

Ultrafast photoinduced phase transitions in complex materials probed by time-resolved resonant soft x-ray diffraction
… new concepts involve the material classes of correlated oxides and materials with antiferromagnetic coupling. Their applicability depends critically on their switching behavior, i.e., how fast and how energy efficient material properties can be manipulated. This thesis presents investigations …

Ferromagnetic manganites: spin-polarized conduction and competing interactions
Electronic properties of solids are vitally important for modern technology, one may think of microelectronics, magnetic data storage, communication technologies and others. Sometimes, it seems possible to postpone the step of fundamental understanding when starting the application of a new …
