    Corroborating the magnetic easy axis of epitaxial (100) α-iron and (0001) BaFe12O19 thin films by 57Fe Mössbauer spectroscopy by Y. E. Li, J. Shine, C. Guguschev, M. Brützam, D. G. Schlom, N. Ravi

    Published 2025-01-01
    “…60 and 120 nm thick epitaxial films of isotopically enriched bcc iron (α-57Fe) grown on (100) MgO substrates are studied using x-ray diffraction, reflection high-energy electron diffraction (RHEED), and conversion electron Mössbauer spectroscopy (CEMS). X-ray diffraction and RHEED data indicate that each film behaves as a single crystal material consistent with the relative intensity ratios of the spectral lines observed in the CEMS spectrum. …”
