摘要
Fe3O4 is one of the important oxide materials and its surface structure should be well understood to enable application of this material. We report the first noncontact atomic force microscopy (NC-AFM) results for Fe3O4(001) thin films. The observed films were grown homoepitaxially on magnetite thin films substrate. A low-energy electron diffraction pattern shows the well-known d ffiffiffi root 2 x root 2)R45 degrees reconstructed structure. The observed minimum step height is 0.21 nm, corresponding to the distance between the same planes. We obtain two types of atomic-scale NC-AFM images. One image shows bright protrusions along the [100] and [010] directions at intervals of 0.84 nm corresponding to a unit cell of the root 2 x root 2)R45 degrees reconstructed structure. The other image shows a more detailed atomic structure with 0.6 and 0.3nm corrugations. (C) 2012 The Japan Society of Applied Physics
