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…
Moment-volume coupling in La(FeSi)
M. E. Gruner, W. Keune, J. Landers +8
We investigate the origin of the volume change and magnetoelastic interaction observed at the magnetic first-order transition in the magnetocaloric system La(FeSi)$_{13…
Impact of lattice dynamics on the phase stability of metamagnetic FeRh: Bulk and thin films
Michael Wolloch, Markus E. Gruner, Werner Keune +20
We present phonon dispersions, element-resolved vibrational density of states (VDOS) and corresponding thermodynamic properties obtained by a combination of density functional theo…
Exo-interferometric Phase Determination of X rays
Wolfgang Sturhahn, Caroline L'abbe, Thomas S. Toellner
The time-dependent phase change of x rays after transmission through a sample has been determined experimentally. We used an x-ray interferometer with a reference sample containing…
Measuring velocity of sound with nuclear resonant inelastic x-ray scattering
Michael Y. Hu, Wolfgang Sturhahn, Thomas S. Toellner +4
Nuclear resonant inelastic x-ray scattering is used to measure the projected partial phonon density of states of materials. A relationship is derived between the low-energy part of…
