Schematics of the relationship between “Skyrmion” proposed originally by Tony Skyrme in 1960s as a mathematical model of baryons in particle physics and “Magnetic Skyrmion” discovered recently in magnets with broken spatial inversion symmetry. The hedgehog-shaped Skyrmion characterized by vector fields which point in all directions wrapping a sphere is connected to the Neel-type and Bloch-type magnetic skyrmions via the stereo projection and the rotation around the z-axis. Recent intensive researches have revealed that the magnetic skyrmions exhibit a lot of intriguing physical phenomena and rich spintronic device functions. (p.460)
