  The structure of the Fe3O4(110)-(1x3) surface was studied with scanning
tunneling microscopy (STM), low-energy electron diffraction (LEED), and
reflection high energy electron diffraction (RHEED). The so-called
one-dimensional reconstruction is characterised by bright rows that extend
hundreds of nanometers in the [1-10] direction and have a periodicity of 2.52
nm in [001] in STM. It is concluded that this reconstruction is the result of a
periodic faceting to expose {111}-type planes with a lower surface energy.
