We are interested in novel spin textures, especially those occurring in three-dimensional magnetic objects such as nanowires, nanotubes and 3D MRAM. In these, specific effects are made possible by curvature, three-dimensional spin and space, and topology with azimuthal periodic boundary conditions. We design and fabricate devices, 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. This research topic is conducted in close collaboration with colleagues in the Theory group, with LEMMA laboratory at IRIG, with Institut Néel, and expert chemist groups in Germany.
Physics of spin textures
We aim at investigating the existence and dynamics of motion of 3D spin textures under magnetic field or spin-polarized current. While nanowires have been the initial focus, we are developing multilayered nanotubes for their higher versatility for spintronic purposes. Checking the strength of topological protection against their transformation or annihilation is a major goal. We also contribute to 3D MRAM development. We combine material synthesis, experimental investigations, and micromagnetic modelling.
Special samples need to be designed and synthesized to stabilize 3D spin textures. They may be based on bottom-up chemical synthesis (anodization, electroplating, electroless deposition, atomic layer deposition) and/or lithography for electrical contacting.
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 electron- and X-ray-based techniques, both in the lab and at external facilities.
