Description du sujet de thèse

Interfacial effects, such as interfacial anisotropy, unidirectional exchange coupling, and the Dzyaloshinskii-Moriya interaction (DMI), are essential for tailoring the behavior of thin magnetic films and are fundamental for advancing spintronic technologies. These effects are amplified in van der Waals (vdW) magnetic materials. These materials offer flat, uniform interfaces and enable integration into heterostructures via exfoliation and stacking. Electric fields are an attractive, fast, and energy-efficient way to dynamically tune DMI and anisotropy. To date, their application has been limited to conventional thin-film magnetic materials, and magnetic vdW systems remain largely unexplored.
Building on our expertise in vdW magnetic systems, we propose to study the effects of electric fields on metal/vdW heterostructures and ultrathin magnetic vdW materials. This thesis project aims to enable precise control of magnetic textures and their dynamics in 2D heterostructures.
The team already has a comprehensive set of technical resources.
We propose a primarily experimental thesis for a doctoral student with a strong background in condensed matter physics (magnetism and electronic properties) and nanoscience. Experiments include growth, sample nanostructuring, magneto-optical Kerr microscopy, Brillouin scattering, transport, and synchrotron-based experiments.
Good teamwork skills are required.
