We present surface X-ray diffraction and fast scanning tunneling microscopy results to elucidate the nature of the surface phase transition on magnetite (001) from a [Formula Omitted] reconstructed to a non-reconstructed surface around 720 K. In situ surface X-ray diffraction at a temperature above...
