skyrmion tubes inside an FeGe sample (IMAGE) Technische Universität Dresden Caption 3D volume representation of the magnetic field of skyrmion tubes inside an FeGe sample. The direction of the magnetic field is color coded and shown in the whole volume. In the cross-section of the sample, the magnetic field is additionally represented by arrows. The distance between two tubes is about 100 nm.
