Nanoscale Confinement Enhances Ultrafast Demagnetization
Yoav William Windsor, Tobias Lojewski, Moumita Kundu +22
Nanoscale miniaturization has revolutionized the field of spintronics by enabling exponential growth in areal bit density. A similar leap is also expected in device speeds through…
Accelerated ultrafast demagnetization of an interlayer-exchange-coupled Co/Mn/Co trilayer
Jendrik Gördes, Ivar Kumberg, Chowdhury S. Awsaf +7
We investigate the ultrafast magnetization dynamics of an interlayer-exchange-coupled Co/Mn/Co trilayer system after excitation with an ultrafast optical pump. We probe element- an…
Simultaneous mapping of the ultrafast time and fluence dependence of the laser-induced insulator-to-metal transition in magnetite
J. O. Schunck, P. S. Miedema, R. Y. Engel +10
Pump-probe methods are a ubiquitous tool in the field of ultrafast dynamic measurements. In recent years, x-ray free-electron laser experiments have gained importance due to their…
First experiments with ultrashort, circularly polarized soft X-ray pulses at FLASH2
S. Marotzke, D. Gupta, R. -P. Wang +23
Time-resolved absorption spectroscopy as well as magnetic circular dichroism with circularly polarized soft X-rays (XAS and XMCD) are powerful tools to probe electronic and magneti…
Femtosecond charge and spin dynamics in CoPt alloys
Martin Pavelka, Simon Marotzke, Ru-Pan Wang +19
The use of advanced X-ray sources plays a key role in the study of dynamic processes in magnetically ordered materials. The progress in X-ray free electron lasers enables the direc…
