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 ${}^{57}$Fe Mössbauer spectroscopy and ${}^{57}$Fe nuclear resonant inelastic x-ray scattering (NRIXS) in nanoscale polycrystalline [bcc-${}^{57}$Fe/MgO] multilayers with vari…
