Micro et NanoMagnétisme - MNM (256)

Goals

The Micro- and NanoMagnetism team works in two main scientific directions, sharing a common experimental and conceptual expertise. The first one is dedicated to the investigation and engineering of functional properties occurring in nanostructured magnetic materials, with special attention paid to their integration in devices for energy and biology related applications. The second one is focused on the study of micromagnetic configurations in thin films and nanostructures, together with their manipulation using magnetic and electric fields or electrical currents.

The magnetisation of thin films can be manipulated not only by magnetic field but also by an electrical current through the so-called spin transfer torque effects. The dynamics of domain walls – the regions that separate magnetic domains- depends on their internal structure: this is determined by the balance between different energy terms i.e. exchange, anisotropy and magnetostatic. In non-centrosymmetric thin films where the magnetic layer is deposited on a heavy metal with large spin-orbit interaction, the presence of interfacial Dzyaloshinskii interaction (DMI) can stabilise magnetic structures with a fixed chirality, skyrmions and domain walls with Néel internal spin structure. The current- and field-driven dynamics of such objects strongly depends on the strength of the DMI. In view of possible applications to spintronic devices, it is important to measure and optimize such interaction.
