Diffuse Electron Scattering from Magnetite above the Verwey Transition Temperature

抄録

Diffuse electron scattering was observed for magnetite just above the Verwey transition temperature. At the (400) type reciprocal lattice points diffuse streaks appeared to stretch along one of the ⟨100⟩ directions when observed for the (001) plane and along the [1\bar10] direction for the (110) plane. No critical scattering was observed at the (200) type reciprocal lattice points which are the characteristic points for the Verway ordering.
