Abstract

The scattering pattern matrix (SPM) method, in combination with multiple-energy holographic patterns, can be used to successfully reconstruct Pt atomic images in FePt epitaxial films, that are almost free from the artifacts that often appear in the images reconstructed using the Barton algorithm. The difference in the chemical short-range-order structure in two FePt films grown at different temperatures was clearly observed. The present method provides us a concrete breakthrough for a quantitative analysis of a three-dimensional local atom arrangement around a certain element in a single crystal without any preliminary knowledge of its structure.
