We are interested in novel spin textures, such as magnetic skyrmions and Bloch-point domain walls, which can be topologically-protected. These involve the three components of magnetization and/or three-dimensional distributions of magnetization. We design the systems, image the spin textures, and ultimately aim at addressing these with spin-polarized currents. The applied background includes the proposed concept of 3D race-track memory.
Physics of spin textures
We aim at investigating the dynamics of motion of 3D spin textures under magnetic field or spin-polarized current. Checking the strength of topological protection against their transformation or annihilation is a major goal. We combine material synthesis, experimental investigations, and micromagnetic modelling.
Special samples need to be designed and synthesized to stabilize 3D spin textures. This involves both multilayer physical deposition, and bottom-up synthesis of nanowires and nanotubes with chemical means.
Advanced magnetic imaging
Magnetic imaging 3D spin textures is demanding in terms of spatial resolution, bulk/surface and multi-components sensitivity. We are developing expertise in various techniques both in the lab and at external facilities.
