Thin films of LSMO (doping value x=0.33 and x=0.35, grown on LSAT(100) and SrTiO (100)) and of (Ga,Mn)As (Mn doping between 8 and 13%, grown on GaAs(100)) were measured. Figure 1 shows the Mn 2p core-level spectra measured for (Ga,Mn)As (panels a and b) and LSMO (panels f and g) epitaxial films, as a function of increasing photon energy, that is, with increasing probing depth20,21. The lattice structures are sketched in Fig.
