Phys.org  May 10, 2024 Through a combination of pulsed currents and reversed magnetic fields, researchers in China experimentally achieved skyrmion bundles with different integer Q values in the chiral magnet Co8Zn10Mn2. They demonstrated the field-driven annihilation of high-Q bundles and presented a phase diagram as a function of temperature and field. Their findings were corroborated by micromagnetic simulations… read more. Open Access TECHNICAL ARTICLE
