Schematic drawing shows an electron (gold sphere) moving in the direction of the green arrow on the surface of a topological crystalline insulator. In this material, the electron’s quantum-mechanical spin (up) (blue arrow) is coupled with the direction of its motion in such a way that reversing its direction of motion would reverse the direction of the spin (down).11.01.15Science Highlight

A stripe-shaped magnetic region (domain), shown in blue (top left) in an ultrathin film device (orange structure). The narrowing region of the device causes the current distribution to change (two of the three red arrows change direction), leading to the breakdown of the magnetic domain into circular disk-shaped bubbles, called skyrmions (bottom left) Magnetic skyrmion bubbles (bottom right) were experimentally observed using magnetic imaging.11.01.15Science Highlight
