Facilitating electrical and laser-induced skyrmion nucleation with a dipolar-field enhanced effective DMI
Mark C. H. de Jong, Dinar Khusyainov, Julian Hintermayr +6
We demonstrate experimentally how the nucleation of skyrmions in an Ir, Co, and Pt based magnetic multilayer is affected by introducing a layer dependent sign for the Dzyaloshinski…

Coherent control of terahertz-scale spin resonances using optical spin-orbit torques
Julian Hintermayr, Paul M. P. van Kuppevelt, Bert Koopmans
Using optically generated spin-orbit torques induced by the heavy metal Pt we demonstrate coherent control of GHz ferromagnetic resonances in Pt/Co/Pt multilayers as well as sub-TH…

Explaining all-optical switching in ferrimagnets with heavy rare-earth elements by varying the spin-flip scattering probability of Gd in CoGd alloys and Co/Gd bilayers
Julian Hintermayr, Bert Koopmans
Using the microscopic three temperature model, we simulate single-pulse all-optical switching (AOS) in alloys and bilayers consisting of Co and Gd. In particular, we investigate it…
