Spintronics Advance: Skyrmions Stablized Above Room Temperature. Chiral magnetic skyrmions -insight from materials specific theory; Alexei N. Magnetic skyrmions are tiny, nanometer-sized magnetic-spin vortices that emerge in magnetic materials. This brief reviews current research on magnetic skyrmions, with emphasis on formation mechanisms, observation techniques, and materials design strategies. In this thesis, we investigate the GHz dynamics of skyrmionic spin structures by CoB/Pt multilayer material for low magnetic pinning, as required for ultrafast. The twisting in the skyrmions' magnetization profile leads to a gain in energy with respect to a homogeneously magnetized, ferromagnetic state. Magnetic skyrmions, which are topological particle-like excitations in ferromagnets, have attracted Skyrmion conversion between different magnetic materials. Nearly seven decades of research on microwave excitations of magnetic materials have led to a wide range of applications in electronics. Stable whirls in magnetic materials (see figure) were predicted over 25 years ago , but the experimental realization was achieved only recently. The excitement is largely due to the potential of magnetic skyrmion materials for storing information in future memory and logical devices. Topologically protected objects which can form in magnetic materials. A new class of chiral materials hosting magnetic skyrmions beyond room temperature. Magnetic vortex structures, so-called skyrmions, could in future store and process information very efficiently. We develop a micromagnetic theory of chiral skyrmions in thin magnetic layers for magnetic materials with intrinsic and induced chirality. Skyrmions, discovered just a few years ago, are tiny islands of magnetism that form in certain materials. Topologically stable magnetic screw-like nanostructures called skyrmions were designed by using the concept of topology and the guidance of theory. Magnetic skyrmions can form in so-called 'bulk' materials such as MnSi, or in magnetic thin films. 5 Key Laboratory of Magnetic Materials and Devices, Ningbo Institute of Material Technology skyrmion driven by a spin wave in a magnetic nanowire. Magnetic skyrmions are tiny, nanometer-sized magnetic-spin vortices that emerge on the surface of magnetic materials.
