Electron Holography

Electron holography, by which the phase shift of the incident electrons is analyzed, visualizes the magnetization distribution in advanced magnetic materials. One particular advantage of electron holography is that unwanted contributions to the contrast which are caused by local variations in composition and sample thickness can, in principle, be removed from a recorded phase image. Electron holography has recently been applied to the characterization of a wide variety of nanostructured materials, including semiconductor devices and quantum well structures, as well as magnetic thin films and nanostructures.
