Chiral Magnetic Skyrmions in Thin Films

摘要: Symmetry breaking together with strong spin-orbit interaction give rise to many exciting phenomena within condensed matter physics. A recent example is the existence of chiral spin textures, which are observed in magnetic systems lacking inversion symmetry. These including domain walls and skyrmions, both fundamentally interesting technologically promising. For example, they can be driven very efficiently by electrical currents, exhibit new physical properties determined their real-space topological characteristics. Depending on details competing interactions, these textures exist different parameter spaces. However, governing mechanism underlying behaviors remain essentially same. In this review article, fundamental physics key factors for materials optimization, current developments future challenges will discussed. end, a few promising directions that advance development skyrmion based spintronics highlighted.
