Electron Diffraction with the Amorphous Alloys Fe80B20 and Mn73Si27

Abstract

Electron diffraction with amorphous Fe80B20 and Mn73Si27 yields structure factors and pair correlation functions which are discussed together with the results of X-ray- and neutron-diffraction experiments. For Mn73Si27 additional interesting details are revealed. A tetrahedral model for Mn73Si27 is described. Finally we show that the evaluation of partial structure factors by the three beam experiment, i.e. the combination of an electron-, X-ray- and neutron-diffraction experiment is not possible in general.
