Paper Abstract
We have measured room temperature x-ray absorption spectroscopy (XAS) at the Mn L2,3edges on ferromagnetic Ga1-xMnxAs films prepared under different As2/Ga flux ratios. A growth
condition relative energy shift (ΔE) at L2 peak was observed, the results suggest that the formation
of antiferromagnetic Mn-As complex under As-rich growth conditions and the energy shift can be
weakened even eliminated by post-growth low temperature (LT) annealing. The intensity of XAS
spectrum was promoted after post-growth annealing, and the effect of annealing was also
influenced by growth conditions.
