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…
