Title: Spin and orbital magnetic moments of ultrathin Fe films on GaAs(100) studied by X-ray magnetic circular dichroism
Abstract: The spin and orbital magnetic moments of 33 and 8 ML epitaxial BCC Fe films grown on GaAs(1 0 0)-4×6 have been measured using X-ray magnetic circular dichroism. Both samples have approximately the same spin moments of about 2.0 μB close to that of the bulk value, which confirms that there are no magnetic dead layers at the interface. A giant orbital moment enhancement of about 300% was observed in the 8 ML film, which may be partially due to an increased degree of localization of electronic states at the Fe/GaAs interface.
