text: L2,3 absorption edges in order to determine the magnetic 
  response of the individual elements. In L2,3 XMCD, elec- 
  trons are excited from a 2p core level to the unoccupied 
  3d valence states of the element of interest by circularly 
  polarized x-rays at the resonance energies of the transi- 
  tions. The diﬀerence in absorption for opposite polariza- 
  tions gives a direct and element-speciﬁc measurement of 
  the projection of the 3d magnetic moment along the x- 
  ray polarization vector. The absorption cross-section is 
  conventionally obtained by measuring the decay products 
  – either ﬂuorescent x-rays or electrons – of the photoex- 
  cited core hole. The type of decay product measured 
  determines the probing depth of the technique. For Mn 
  L2,3 absorption, the probing depths for FY and TEY de- 
  tection are λF Y ≈ 100 nm and λT EY ≈ 3 nm. 
  In the 
  current experiment, the Mn XMCD measured using FY 
  and TEY are thus sensitive to the bulk of the (Ga,Mn)As 
  ﬁlm and the near-interface layers, respectively.
