Query: Creation of Single Chain of Nanoscale Skyrmion Bubbles with Record-high
  Temperature Stability in a Geometrically Confined Nanostripe   Nanoscale topologically non-trivial spin textures, such as magnetic
skyrmions, have been identified as promising candidates for the transport and
storage of information for spintronic applications, notably magnetic racetrack
memory devices. The design and realization of single skyrmion chain at room
temperature (RT) and above in the low-dimensional nanostructures are of great
importance for future practical applications. Here, we report the creation of a
single skyrmion bubble chain in a geometrically confined Fe3Sn2 nanostripe with
a width comparable to the featured size of a skyrmion bubble. Systematic
investigations on the thermal stability have revealed that the single chain of
skyrmion bubbles can keep stable at temperatures varying from RT up to a
record-high temperature of 630 K. This extreme stability can be ascribed to the
weak temperature-dependent magnetic anisotropy and the formation of edge states
at the boundaries of the nanostripes. The realization of the highly stable
skyrmion bubble chain in a geometrically confined nanostructure is a very
important step towards the application of skyrmion-based spintronic devices.
