摘要：

Fe3O4 (magnetite) has been suggested as a half-metal material. On the other hand, Mn3O4 has an extremely strong anisotropy effect. Using plasma-oxygen-assisted molecular beam epitaxy, we are able to grow Fe3O4, Mn3O4 and a series of Fe3-x, MnxO4 (0 less than or equal to x less than or equal to 3) films on MgO (0 0 1) and (0 1 1), with epitaxial quality. A cubic-to-tetragonal structural transformation is observed first time in Fe3-x, MnxO4 films. The magnetic response also shows an abrupt change of magnetic anisotropy and high coercivity, which is consistent with structural transition. (C) 2004 Published by Elsevier B.V.
