Magnetic moment distribution within the Skyrmion. Yellow and blue colors in (a) represent schematically the region giving gain and loss of Zeeman energy in the presence of a magnetic field; blue color in (b) shows the region giving loss of the exchange energy contributed by in-plane components of magnetic moments. (c) and (d): Structure of single Sk obtained with the contributions of the Fe-Pt exchange interactions taken into account [the same color code as in (a) and (b)].

Three simple experiments that illustrate the resistance to deformation of assemblies of ferromagnetic spheres. (a) The self-buckling of a vertical chain of magnetic spheres as further spheres are added. (b) The prolate–oblate oscillation of a ring of magnetic spheres. Snap-shots of the motion are shown at intervals of 0.021 s. (c) A self-assembled chiral ‘nano-tube’. In each case, the diameter of the spheres is 2a=5 mm and the magnetic field strength is B= 1.195 T.
