About the project:

Seeing Magnetism in 3D: Ptychographic Electron Tomography of Nanostructured Spin Textures

Supervisor: Dr Peng Wang, University of Warwick

Magnetic skyrmions are tiny whirlpools of spins that could form the basis of future low-power data storage devices. However, real skyrmions are three-dimensional and can twist, stretch, or deform when trapped by material defects - behaviour that is still poorly understood.

This project will develop advanced computational models to simulate a new imaging technique called electron ptychography, which can map magnetic fields in 3D at nanometre resolution.

By combining quantum-mechanical modelling, tomographic reconstruction, and data-science methods, the project will reveal how skyrmions interact with defects, helping to design the next generation of magnetic materials.
