      abstract     = {Understanding the fundamental spin coupling mechanisms
                      indilute magnetic oxides is not possible without exact
                      atomistic understanding ofthe solids. This is even more
                      important for few systems that show diluteferromagnetism at
                      room temperature and could potentially be used in
                      spintronicand multiferroic technologies. Here, we show the
                      first known example of a cationordering in hexagonal
                      6H-perovskites. Fe3+ ions in Fe-doped 6H-BaTiO3 areinitially
                      randomly distributed over two Ti4+ crystallographic sites
                      but can be, by aprolonged heat treatment, ordered onto one
                      of the sites. The cation ordering isdriven by reduction in
                      the electrostatic repulsion, which occurs when
                      Fe3+substitutes the highly charged Ti4+ ions that are
                      located at unusual proximity toeach other. We show that such
                      a continuous order−disorder transition isassociated with
                      induction of the room-temperature dilute ferromagnetism.},
