Studying all-optical magnetization switching of GdFe by double-pulse laser excitation
Rahil Hosseinifar, Felix Steinbach, Ivar Kumberg +11
The tremendous interest in the technology and underlying physics of all-optical switching of magnetization brings up the question of how fast the switching can occur and how high t…
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…
Element-selective probing of ultrafast ferromagnetic--antiferromagnetic order dynamics in Fe/CoO bilayers
Chowdhury S. Awsaf, Sangeeta Thakur, Markus WeiÃenhofer +6
The ultrafast magnetization dynamics of an epitaxial Fe/CoO bilayer on Ag(001) is examined in an element-resolved way by resonant soft-x-ray reflectivity. The transient magnetic li…
Giant Rashba-Splitting of One-Dimensional Metallic States in Bi Dimer Lines on InAs(100)
Polina M. Sheverdyaeva, Gustav Bihlmayer, Silvio Modesti +12
Bismuth produces different types of ordered superstructures on the InAs(100) surface, depending on the growth procedure and coverage. The (2x1) phase forms at completion of a Bi mo…
