Description
Magnonic crystals are a novel type of artificial crystals formed by the periodic arrangement of magnetic nanostructures and magnetic skyrmions [1] are topologically stable spin textures, generally stabilized by Dzyaloshinskii-Moriya interactions [2]. Key challenges regarding the skyrmion lattice are to stabilize and confine them. The aim of the present work is to stabilize and confine the magnetic skyrmions by patterning a nanometer size antidot lattice in high perpendicular magnetic anisotropy films. The observations are very important for future magnon spintronic devices based on skyrmion lattices.
