Influence of hydrogenation on the vibrational density of states of magnetocaloric LaFe11.4Si1.6 H 1.6

We report on the impact of magnetoelastic coupling on the magnetocaloric properties of LaFe11.4Si1.6H1.6 in terms of the vibrational (phonon) density of states (VDOS), which we determined with 57Fe nuclear resonant inelastic x-ray scattering (NRIXS) measurements and with density functional theory (D...
