                      performance of catalysts anddevices [1,2,3]. We exemplarily
                      studied the homoepitaxial growth ofFe3−𝛿O4 (001) in
                      dependence of the O2 pressure and iron flux. Xrayintensity
                      growth oscillations proved ordered growth of Fe3−𝛿O4for
                      all probed conditions while atomic force microscopy revealed
                      newlyformed micrometre-sized surface structures exceeding
                      the amount ofdeposited material [4]. Our results indicate
                      the presence of multipleparallel processes during reactive
