Magnetic skyrmions, which are topological spin configuration, have gained interest in the past few years. However, skyrmions suffer from the skyrmion Hall effect, a phenomenon where skyrmions deflect from the path of the electron flow and annihilate at the edge of the track. There are attempts ...
the concept of racetrack memory 9 , in which a train of up and down magnetic domains is moved electrically along a magnetic track, could be extended to ultrahigh-density information-storage devices based on the manipulation of skyrmions in nanotracks 7,8 . Magnetic skyrmions 10 are chiral spin...
Magnetic skyrmions are nanoscale spin configurations that hold promise as information carriers in ultradense memory and logic devices owing to the extremely low spin-polarized currents needed to move them.

Here, we unveil the motion of individual 80 nm-size skyrmions in an FeGe track with an ultrathin width of 100 nm. The skyrmions can move steadily along the track over a broad range of current densities by using controlled pulse durations of as low as 2 ns. The potential landscape...

The TMR detection of mobile skyrmions is also repetitively conducted for the same device under 0.35 kOe and in MTJs with different pillar sizes (Supplementary Note9). There, one can consistently observe the emergence of discrete plateaus after applying current pulses along the bottom track. Thro...
