(2001) Giant enhancement of orbital moments and perpendicular anisotropy in epitaxial Fe/GaAs(100). Journal of Applied Physics, 89 (11). pp. 7156-7158.

The spin and orbital magnetic moments and the perpendicular magnetic anisotropy of 8 and 33 monolayer epitaxial bcc Fe films grown on GaAs(100)-4×6 have been measured using x-ray magnetic circular dichronism and polar magneto-optical Kerr effect. Both the films have approximately the same spin moments of about 2.0µB close to that of the bulk value. The ultrathin film shows a giant orbital moment enhancement of about 300% with respect to the bulk value and a perpendicular interface anisotropy field H/s(Fe-GaAs) of the order of –5×10(4) Oe. This may be partially due to an increased degree of localization of electronic states at the Fe/GaAs interface associated with the atomic scale interface structure. © 2001 American Institute of Physics.
