Spectroscopic probe of ultrafast magnetization dynamics in the extreme ultraviolet spectral range
Johanna Richter, Somnath Jana, Robert Behrends +6
The development of spectroscopic techniques in the extreme ultraviolet (XUV) spectral range has significantly advanced the understanding of ultrafast interactions in magnetic syste…
Fluence dependent delay of Ni in an FeNi alloy supports an exchange based origin
Somnath Jana, Ronny Knut, Puloma Singh +9
The delayed demagnetization in Ni relative to Fe in the ultrafast demagnetization studies in FeNi alloy has led to two competing theoretical explanations: The Inhomogeneous Magnon…
Sub-wavelength localized all-optical helicity-independent magnetic switching using plasmonic gold nanostructures
Themistoklis Sidiropoulos, Puloma Singh, Tino Noll +8
All-optical helicity-independent switching (AO-HIS) is of interest for ultrafast and energy efficient magnetic switching in future magnetic data storage approaches. Yet, to achieve…
