We are interested in novel spin textures, especially those occurring in three-dimensional (3D) magnetic objects. Curvature, domain walls, 3D spin and space, topology are some of our daily words at work.  We design and fabricate devices, image their spin textures and influence these with spin-polarized currents or externally applied magnetic fields. The applied background includes the proposed concept of 3D race-track memory. This research topic is driven in close collaboration with colleagues in the Theory group, PFNC at Minatec, Institut Néel, and expert chemist groups in Germany and Spain.

Research topics

Spin textures by models

We investigate the existence, energetics and dynamics of 3D spin textures under magnetic field and spin-polarized current by using and developing our home-made feeLLGood micromagnetic code, combined with analytical modeling.

Spin textures by experiments

From nanowires to multilayered nanotubes, we observe samples compliant for spintronic devices. Probing the strength of a spin texture’s topological protection against transformation or annihilation is a major goal. We also contribute to the development of 3D MRAM (MRAM team).

Material research

We design and synthesize samples to stabilize 3D spin textures using bottom-up chemical synthesis (anodization, electroplating, electroless deposition, atomic layer deposition). We further use lithography/FIB for electrical contacting and design specific sample supports for original in-situ experiments.

Magnetic imaging

Magnetic imaging of 3D spin textures requires high spatial resolution (nanoscale) as well as bulk/surface and multi-component sensitivity. We are developing expertise in electron-, X-ray & near-field probes, both in the lab and at external facilities, including development of instruments and image data treatment.
