The EMA Young Scientist Award 2025 has been awarded to Johanna Fischer, in recognition of her contributions to the field of multiferroics and magnetic skyrmions. With her combined theoretical and experimental perspective, she has demonstrated a clear vision for advancing topological spin textures towards real-world applications. More information (in French): press release of CNRS. Congratulations!

2D materials and van der Waals (vdW) heterostructures are promising candidates to build efficient THz spintronic emitters. Here, we demonstrate the drastic modification of THz spintronic emission by inserting a single layer of MoSe2 in the PtSe2/graphene vdW heterostructure. Ab initio calculations indeed show the emergence of Rashba states due to the electronic hybridization between […]

Time-resolved magnetic helicoidal dichroism (MHD) was successfully used to assess the ultra-fast dynamics of magnetization. This first attempt to use an MHD-based technique was demonstrated on a magnetic vortex structure hosted by a permalloy pacman micropillar (diameter~15nm, thickness~80nm). Micromagnetic simulations allowed to link the features identified in the MHD signal to a process of regeneration […]

Superparamagnetic tunnel junctions have emerged as promising stochastic neurons for low-energy cognitive computing. We report, for the first time, nanosecond-scale mean waiting times between magnetization reversals in perpendicularly magnetized tunnel junctions, enabled by a strong entropic contribution to the thermally activated switching dynamics.   Magnetic tunnel junctions (MTJs) consist of a free and a fixed […]

The modulation of THz spintronic emitters represents a real challenge nowadays. Here, we consider a THz emitter made of 2D materials grown by molecular beam epitaxy (MBE) on large area and transferred on LiNbO3. The low dimensional character makes this system sensitive to the ferroelectric polarization of LiNbO3. Using this proximity effect, we demonstrate the […]

Topology is a powerful tool for categorizing magnetization textures by defining a topological index in both two-dimensional (2D) systems, such as thin films or curved surfaces, and in 3D bulk systems. In the emerging field of 3D nanomagnetism, both volume and surface topological numbers must be considered, requiring the identification of a proper global topological […]
