  • Topologically protected states with a natural helicity are shown to form at step edges, which can be created with subnanometre precision in a weak topological insulator using atomic force microscopy.

  • Magnetic vortices such as skyrmions are promising for spintronic applications, however, little is known about the pinning effects strongly influencing their dynamics. Here, the authors map the interaction potential between defects and vortex cores down to the sub-nanometer scale enabling the better control of these magnetic textures.

  • In principle skyrmions are topologically protected, but the crystal lattice interferes with this protection so that they should be unstable to switching of their winding number. Here this process is understood via scanning tunnelling microscopy.
