Materials hosting magnetic skyrmions at room temperature could enable compact and energetically efficient storage such as racetrack memories. However, avoiding modifications of the inter-skyrmion distances remains challenging. An international team of researchers (Switzerland, Greece, Austria, Italy) has demonstrated that a hybrid ferro/ferri/ferromagnetic multilayer system can host two distinct skyrmion phases at room temperature, namely tubular and partial skyrmions. Furthermore, the tubular skyrmion can be converted into a partial skyrmion. Such systems may serve as a platform for designing memory applications using distinct skyrmion types…read more.
