Tuesday publication post! 📖 This latest research sheds new light on the dynamic behavior of magnetic skyrmions, offering insights into their deformation under electric currents! The authors from the #MaxPlanckInstitute in Halle used the #FusionAX system to apply electronic biasing to isolated skyrmions!
⚡They observed that isolated skyrmions in Co10Zn10 at room temperature deform readily into elliptical shapes when subjected to electric currents.
🔬 The deformation axis rotates consistently toward the current direction, regardless of polarity, and reverses upon current cessation.
📊 Average deformation increased by ~90% at the highest applied current density of |j| = 8.46 × 10⁹ A/m².
📈Skyrmion core size expanded by ~120% during current application, highlighting their topological robustness.
This study provides the first quantitative evaluation of skyrmion deformation induced by electric currents, obtaining better control over spin-polarized electron interactions. These insights are critical for developing efficient, scalable spintronic devices that leverage skyrmions’ unique properties.
