      abstract     = {We have grown an ultra-thin film of iron oxide by oxidising
                      a smooth epitaxial 5 ML Fe film which was deposited on
                      Cu(110). In order to prevent roughening of the Fe film, the
                      oxidation of the iron took place at 130 K. At low oxygen
                      exposures, <2 x 10(-6) mbars, a surface oxide forms. After
                      completion of the surface oxide layer a disordered Fe2O3
                      film grows. Upon annealing, ordering of the oxide film is
                      observed at temperatures above 400 K. A Fe2O3 film With a
                      very well ordered surface could be produced by heating the
                      disordered oxide film. The ordered oxide surface shows a (21
                      x 6) reconstruction, which is interpreted as a coincidence
                      lattice of the Cu(110) substrate and it Fe2O3(111) lattice
                      which is slightly distorted due to a misfit with the
                      substrate $(0.7-2\%)$ and to a misalignment between the
                      major crystallographic axes of the lattices. When the oxide
                      film is slowly heated, decomposition of the oxide takes
                      place in two stages: Between 550 and 700 K, the Fe2O3 film
                      decomposes due to a reaction of this oxide with a buried
                      layer of Fe or FeO. Between 700 and 800 K a further
                      decomposition of the Fe2O3 is found, but now accompanied by
                      desorption of oxygen and solution of Fe in the Cu substrate.
                      The amount of oxygen and iron on the surface keeps on
                      decreasing after the almost complete decomposition of Fe2O3
                      (at 800 K) until a new phase is obtained which is stable
                      between 950 and 1100 K, This high temperature phase (T > 950
                      K) shows a (n x 8) reconstruction with n = 17-19. This
                      reconstruction is interpreted as the result of a coincidence
                      lattice of the Cu(110) substrate with a distorted FeO(111)
                      lattice. (C) 2001 Elsevier Science B.V. All rights
