Grazing-incidence 57Fe-SR-Mössbauer spectroscopy of a 57Fe 95%-enriched 57Fe(100 nm)/MgO(001) film. (a) Experimental set-up. NBM: nuclear Bragg monochromator; S: slit 0.5 mm (V) × 1.0 mm (H); D: NaI(Tl) detector. (b) Reflectivity spectra of the magnetized iron thin film at a grazing angle of 0.3°. Upper and lower parts correspond to the spectrum measured with the non-polarized and right circularly polarized 57Fe-SR-Mössbauer radiation, respectively. The magnetic moment (hyperfine field) of the iron thin film has been aligned antiparallel (parallel) to the beam direction by applying an external magnetic field (Hex = 600 Oe) in the film plane.
