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…
