Mapping the energy-time landscape of spins with helical X-rays
N. Pontius, J. K. Dewhurst, C. Schuessler-Langeheine +5
Unveiling the key mechanisms that determine optically driven spin dynamics is essential both to probe the fundamental nature of ultrafast light-matter interactions, but also to dri…
Using the photo-induced resonance shift in Fe and Ni as time reference for ultrafast experiments at low flux soft X-ray sources
Somnath Jana, Shreyas Muralidhar, Johan Åkerman +2
We study the optical-pump induced ultrafast transient change of the X-ray absorption at the absorption resonances of the transition metals Ni and Fe in FeNi a…
Accelerating the laser-induced demagnetization of a ferromagnetic film by antiferromagnetic order in an adjacent layer
Ivar Kumberg, Evangelos Golias, Niko Pontius +8
We study the ultrafast demagnetization of Ni/NiMn and Co/NiMn ferromagnetic/antiferromagnetic bilayer systems after excitation by a laser pulse. We probe the ferromagnetic order of…
Ultrafast optically induced ferromagnetic state in an elemental antiferromagnet
E. Golias, I. Kumberg, I. Gelen +9
We present evidence for an ultrafast optically induced ferromagnetic alignment of antiferromagnetic Mn in Co/Mn multilayers. We observe the transient ferromagnetic signal at the ar…
Deterministic control of an antiferromagnetic spin arrangement using ultrafast optical excitation
Y. W. Windsor, A. Ernst, K. Kummer +8
A central prospect of antiferromagnetic spintronics is to exploit magnetic properties that are unavailable with ferromagnets. However, this poses the challenge of accessing such pr…
Element-resolved ultrafast demagnetization rates in ferrimagnetic CoDy
T. Ferte, N. Bergeard, L. Le Guyader +7
Femtosecond laser induced ultrafast magnetization dynamics have been studied in multisublattice CoxDy1-x alloys. By performing element and time-resolved X-ray spectroscopy, we dist…
