Influence of magnetic domain walls on all-optical magnetic toggle switching in a ferrimagnetic GdFe film
Rahil Hosseinifar, Evangelos Golias, Ivar Kumberg +7
We present a microscopic magnetic domain imaging study of single-shot all-optical magnetic toggle switching of a ferrimagnetic GdFe film with out-of-plane easy axis o…
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…
Band renormalization of blue phosphorus on Au(111)
E. Golias, M. Krivenkov, A. Varykhalov +2
Most recently, theoretical calculations predicted the stability of a novel two-dimensional phosphorus honeycomb lattice named blue phosphorus. Here, we report on the growth of blue…
Laser-induced persistent photovoltage on the surface of a ternary topological insulator at room temperature
J. Sánchez-Barriga, M. Battiato, E. Golias +4
Using time- and angle-resolved photoemission, we investigate the ultrafast response of excited electrons in the ternary topological insulator (BiSb)Te to fs-i…
Sub-picosecond spin dynamics of excited states in the topological insulator BiTe
J. Sánchez-Barriga, M. Battiato, M. Krivenkov +9
Using time-, spin- and angle-resolved photoemission, we investigate the ultrafast spin dynamics of hot electrons on the surface of the topological insulator BiTe following…
