abstract = {A target Skyrmion is a flux-closed spin texture that has
twofold degeneracy and is promising as a binary state in
next generation universal memories. Although its formation
in nanopatterned chiral magnets has been predicted, its
observation has remained challenging. Here, we use off-axis
electron holography to record images of target Skyrmions in
a 160-nm-diameter nanodisk of the chiral magnet FeGe. We
compare experimental measurements with numerical
simulations, demonstrate switching between two stable
degenerate target Skyrmion ground states that have opposite
polarities and rotation senses, and discuss the observed
switching mechanism.},
