Skyrmion-(anti) vortex coupling in a chiral magnet-superconductor heterostructure

AP Petrović, M Raju, XY Tee, A Louat… - Physical Review Letters, 2021 - APS
We report experimental coupling of chiral magnetism and superconductivity in [IrFeCoPt]/Nb
heterostructures. The stray field of skyrmions with radius≈ 50 nm is sufficient to nucleate …
