We have used x-ray magnetic circular dichroism, which offers a unique capability to give element specific information at submonolayer sensitivity, to determine the spin and orbital magnetic moments at the Fe/GaAs(100) interface. The wedge samples, grown by molecular beam epitaxy at room temperature, consisted of 0.25–1 monolayer (ML) Fe on GaAs(100)-4×6 capped with 9 ML Co and have shown Fe spin moments of (1.84–1.96)μB and a large orbital enhancement. Our results demonstrate unambiguously that the Fe/GaAs(100)-4×6 interface is ferromagnetic with a bulklike spin moment, which is highly promising for spintronics applications.
