“…The data is fit to a Stoner-Wohlfarth (SW) astroid model [16][17][18][19] of the projection of the magnetization along the analysis (photon propagation) direction. The SW model was developed for single domain magnetic particles but has been successfully used for thin film systems where the domains FIG.…”

The elemental perpendicular magnetic anisotropy constants of both elements of a 20 nm bcc Co88Mn12 alloy film grown on MgO(001) and capped with Al, have been determined. By fitting a Stoner-Wohlfarth astroid model to the measured Co and Mn L3 XMCD peak intensities as a function of incidence photon angle with the magnetic field applied co-axially with the photon propagation direction, the elemental perpendicular anisotropy constants were found to be −6.46 x 105 J/m3 and −6.68 x 105 J/m3, respectively. The modeling of the Co and Mn data both result in nearly the same anisotropy constant as expected for a single alloy film.

“…Here we report the determination of elemental PMA constants for a bcc Co 88 Mn 12 magnetic alloy film from the variation of the elemental XMCD signal with the applied magnetic field (both magnitude and direction out of the film plane) through a comparison to the Stoner-Wohlfarth astroid modeling of the magnetization.
