Influence of hydrogenation on the vibrational density of states of magnetocaloric
Alexandra Terwey, Markus E. Gruner, Werner Keune +14
We report on the impact of magnetoelastic coupling on the magnetocaloric properties of LaFeSiH in terms of the vibrational density of states, which we dete…
Effect of lattice excitations on transient near edge X-ray absorption spectroscopy
N. Rothenbach, M. E. Gruner, K. Ollefs +17
Time-dependent and constituent-specific spectral changes in soft near edge X-ray spectroscopy (XAS) of an [Fe/MgO] metal/insulator heterostructure upon laser excitation are ana…
Interface-related magnetic and vibrational properties in Fe/MgO heterostructures from nuclear resonant spectroscopy and first-principles calculations
Benedikt Eggert, Markus E. Gruner, Katharina Ollefs +11
We combine Fe Mössbauer spectroscopy and Fe nuclear resonant inelastic x-ray scattering (NRIXS) in nanoscale polycrystalline [bcc-Fe/MgO] multilayers with vari…
Role of the exchange-correlation functional on the structural, electronic and optical properties of cubic and tetragonal SrTiO including many-body effects
Vijaya Begum, Markus Ernst Gruner, Rossitza Pentcheva
SrTiO is a model perovskite compound with unique properties and technological relevance. At 105 K it undergoes a transition from a cubic to a tetragonal phase with characterist…
Epitaxial strain adaption in chemically disordered FeRh thin films
Ralf Witte, Robert Kruk, Di Wang +5
Strain and strain adaption mechanisms in modern functional materials are of crucial importance for their performance. Understanding these mechanisms will advance innovative approac…
Microscopic non-equilibrium energy transfer dynamics in a photoexcited metal/insulator heterostructure
N. Rothenbach, M. E. Gruner, K. Ollefs +15
The element specificity of soft X-ray spectroscopy makes it an ideal tool for analyzing the microscopic origin of ultrafast dynamics induced by localized optical excitation in meta…
Dynamics of optical excitations in a Fe/MgO(001) heterostructure from time-dependent density functional theory
Markus Ernst Gruner, Rossitza Pentcheva
In the framework of real-time time-dependent density functional theory (RT-TDDFT) we unravel the layer-resolved dynamics of the electronic structure of a (Fe)/(MgO)(001) mu…
