RESEARCH INTERESTS

We investigate topological magnetism and novel spin textures, focusing on the creation, manipulation, and dynamics of skyrmion and antiskyrmion structures under external stimuli. Our research integrates in situ L-TEM, 3D electron tomography, 4D-STEM, and micromagnetic simulations to reconstruct spin textures and uncover their underlying mechanisms. Our goal is to advance the fundamental understanding of emergent topological states and their field-driven phase transitions toward future spintronic applications.

Research Interests include:

1. Topological spin textures

2. Topological magnetic materials, 2D magnetic materials

3. In situ Lorentz TEM

4. 3D magnetism tomography and 4D-STEM

5. Spintronic devices
