      abstract     = {Element specific magnetization has been determined at the
                      surface and in the bulk of Co2Cr0.6Fe0.4Al Heusler alloy
                      films grown on alpha-Al2O3 and capped by Al, using x-ray
                      magnetic circular dichroism both in transmission and total
                      electron yield. The magnetic moments for Co and Fe are
                      considerably reduced at the upper surface in comparison to
                      their values in the bulk of the film. The large reduction at
                      room temperature of $17\%$ for thick films averaged along
                      the electron escape depth implies an even larger reduction
                      at the topmost layer which is crucial for spin-dependent
                      transport. The surface magnetization decreases additionally
                      with respect to the bulk value with decreasing film
                      thickness below 20 nm.},
