Using spin-density functional theory we investigated various possiblestructures of the hematite (0001) surface. Depending on the ambient oxygenpartial pressure, two geometries are found to be particularly stable underthermal equilibrium: one being terminated by iron and the other by oxygen. Bothexhibit huge surface relaxations (-57 % for the Fe- and -79 % for theO-termination) with important consequences for the surface electronic andmagnetic properties. With scanning tunneling microscopy we observe twodifferent surface terminations coexisting on single crystalline alpha-Fe_2 O_3(0001) films, which were prepared in high oxygen pressures.
