Magnetic skyrmions are tiny, nanometer-sized magnetic-spin vortices that emerge in magnetic materials. The twisting in the skyrmions' magnetization profile leads to a gain in energy with respect to a homogeneously magnetized, ferromagnetic state. The spins themselves stay put—it's the pattern that moves. Stable whirls in magnetic materials (see figure) were predicted over 25 years ago , but the experimental realization was achieved only recently. These results show that skyrmion materials with rich physical properties can be found among frustrated magnets. In close relationship with imec's magnetic memory and magnetic logic programs, you will aim at introducing skyrmions in materials of interest in spintronics. Scientists have found a way to manipulate tiny magnetic vortices known as skyrmions using mechanical energy. Journal of Magnetism and Magnetic Materials (Impact Factor: 1.97). (A) Sketch of a magnetic skyrmion, a knot in the magnetization with a defined twist. Publication » Discrete double core skyrmions in magnetic thin films. This brief reviews current research on magnetic skyrmions, with emphasis on formation mechanisms, observation techniques, and materials design strategies. Sometimes, the spins in a magnetic material will form tiny swirls that can move around like particles. Spintronics Advance: Skyrmions Stablized Above Room Temperature. Light blue arrows show the in-plane magnetization direction of the DW [as shown in the 2 Experimental generation of magnetic skyrmions. Magnetic skyrmions, which are topological particle-like excitations in ferromagnets, have attracted Skyrmion conversion between different magnetic materials. Skyrmions for future storage devices.
