Scanning Transmission Electron Microscopy of Electromagnetic Structure.
Abstract
The report describes the application of Lorentz electron microscopy to the study of structural changes of amorphous alloys in composition region approximately Fe80B20. Significant changes in the magnetic domain structure can in certain instances be associated with phase transitions, segregation and stress effects together with changes in the amorphicity. The appearance of magnetization ripple and the formation of regular stripe domain patterns are examples of the magnetic structures which can be observed by defocussing the electron microscope in the transmission mode. Parallel observations have been made using established X-ray and electron diffraction crystallographic techniques, Mossbauer effect and differential scanning calorimetry. (Author)
