(i). Skyrmions in multilayer films
By using MFM, L-TEM, MOKE, and micromagnetic simulations, we investigated the creation, chirality, density and the current driven dynamics of the Néel-type skyrmions in [Pt/Co/Ta]n multilayer stacks.
(ii). Skyrmions in bulk materials
By using FIB and LTEM, we investigated the Biskyrmions in MnNiGa magnet and the bloch-type skyrmions in a frustrated kagome magnet Fe3Sn2. The current induced skyrmion dynamics in a nanostripe is also investigated.
