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…
