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…
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…
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…
Element-resolved thermodynamics of magnetocaloric LaFeSi
M. E. Gruner, W. Keune, B. Roldan Cuenya +10
By combination of two independent approaches, nuclear resonant inelastic X-ray scattering and first-principles calculations in the framework of density functional theory, we determ…
A general moment NRIXS approach to the determination of equilibrium Fe isotopic fractionation factors: application to goethite and jarosite
N. Dauphas, M. Roskosz, E. E. Alp +7
We measured the reduced partition function ratios for iron isotopes in goethite FeO(OH), potassium-jarosite KFe3(SO4)2(OH)6, and hydronium-jarosite (H3O)Fe3(SO4)2(OH)6, by Nuclear…
Thermal Expansion of Germanium Isotopes at Low Temperature
R. Colella, B. Reinhart, E. Alp +1
The focus of this paper is the vanishing of the thermal expansion in certain diamond-like semiconductors. In silicon becomes zero at T = 122. K. In germanium the situation is less…
