Experimental measurement of electron diffuse scattering in magnetite using energy-filter and imaging plates

Abstract

We have measured the diffuse scattering in magnetite as a function of temperature using the LEO 912Ω energy-filtering electron microscope and the imaging plates. This study takes the advantage of the Koehler illumination system, energy filtering and the imaging plates for recording electron diffraction pattern over a large dynamic range. The experiment clearly shows a quantitative change in diffuse scattering distribution, which has the characteristics of one-dimensional ordering. This study clearly demonstrates the possibility for the quantitative study of diffuse scattering using electron diffraction.
