Skyrmions are topological solitons hosted in thin magnetic films with broken inversion symmetry. The critical issue in the formation of skyrmions is the Dzyaloshinskii–Moriya (DM) interaction leading to the non-conventional magnetic order. Modern spintronics hopes that skyrmions will replace domain walls in memory storage devices. Certainly, skyrmions have higher mobility and other advantages as compared to the domain walls. The manipulation of skyrmions, skyrmion confinement and drag are vital issues.
The second challenge in skyrmionics is downscaling the size of the skyrmions. Physical features of the quantum skyrmions have attracted colossal interest recently. Experimental measurements performed on the skyrmions for analyzing the surface morphology may exert invasive effects on quantum skyrmions. In the present talk, we discuss several aspects of modern skyrmionics, manipulation and tweezing of skyrmions, general problems of quantum metrology, quantum correlations, and entanglement.
