Element resolved evidence of superdiffusive terahertz spin current arising from ultrafast demagnetization process
R. Gupta, F. Cosco, R. S. Malik +13
Using element-specific measurements of the ultrafast demagnetization of Ru/FeCo heterostructures, we show that Ru can exhibit a significant magnetic contrast (3% asym…

Ultrafast manipulation of the NiO antiferromagnetic order via sub-gap optical excitation
Xiaocui Wang, Robin Y. Engel, Igor Vaskivskyi +19
Wide-band-gap insulators such as NiO offer the exciting prospect of coherently manipulating electronic correlations with strong optical fields. Contrary to metals where rapid depha…
