Abstract

Significance: The rapid growth of data volume demands faster and denser storage devices. The noncoplanar swirling spin texture, known as magnetic skyrmion, has potential application in future memory devices. To realize such applications, it is essential to understand the properties of individual skyrmion in patterned nanoelements. While quite a number of theoretical efforts have been made in this field, direct experimental demonstration in such a real modeling system is a challenge. Here, we report the direct visualization of skyrmion cluster states in FeGe nanodisks. We determine the common relationship among the temperature, magnetic field, and disk size. These results have an immediate implication for designing future skyrmion-based devices.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
