Interface-induced skyrmions in magnetic films and multilayers

The talk is on individual skyrmions induced by interface Dzyaloshinskii-Moriya Interactions (DMI) in thin magnetic films or multilayers. I will present: \begin{enumerate} \item Ab-initio calculations of the characteristic features of interface DMI [1]: extension of the DMI away from the interface in the magnetic film, thickness dependence, influence of the existence of proximity-induced magnetism in neighbor layers, influence of interface roughness, perspective with new materials\textellipsis \item Experimental results on small skyrmions at room temperature in (Ir/Co/Pt)x10 multilayers [2]. \item Towards applied devices: micromagnetic simulations of the nucleation and current-induced motion of skyrmions [3]. \end{enumerate} [1] H.
