Beschreibung:
Information processing and storage applications demand increasing miniaturization and operation speeds, where optical manipulation of magnetic order may play a very important role. It is hence essential to study how light stimulates magnetization reordering at very short spatial and temporal scales. The development of Ultrafast Transmission Electron Microscopy (UTEM), a laser-pump/electron-probe setup, provides a unique means for that. However, magnetic information can only be visualized in UTEM provided a spatially coherent pulsed electron source is available, since phase-contrast techniqu...
