We present a surface science study on carefully characterized GaxMn1−xAs films grown on GaAs(100), where we investigate the influence on magnetic properties of different surface cleaning procedures. X-ray magnetic circular dichroism reveals a net remnant magnetization along the (100) axis, after chemical etching is performed. The analysis of Mn L2,3 XAS line shapes in different environment ...
