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…
Local excitons in silicon induced by SiGe quantum huts
Arka Bikash Dey, Milan K Sanyal, Swapnil Patil +4
Conversion of Si to a direct bandgap semiconductor for optoelectronic application is a great challenge for many decades. It is proposed that embedment of suitable sized quantum dot…
