In Ta/FeCoB/TaOx, it was demonstrated that the Dzyaloshinskii-Moriya interaction (DMI) chirality can undergo modification solely in response to variations in the thickness of the ferromagnetic layer. This inversion of chirality is attributed to variations in orbital filling and interatomic distances at the interface, driven by the structural relaxations in the ultrathin regime. This method provides […]

Van der Waals magnets are typically limited to low-temperature and multilayer form. Here, we first demonstrated room-temperature ferromagnetism in thicker Co-doped Fe₅GeTe₂ films, then achieved ferromagnetism up to ∼200 K in epitaxial monolayers, a breakthrough for two-dimensional spintronics. Two-dimensional (2D) van der Waals (vdW) magnets are highly sought after for their potential in spintronics. Their […]

Position: The project FLUSPIN is opening a 12-month position (possible extensions) for a postdoctoral researcher to explore the integration of Kramers-type thermal activation theories—validated for equilibrium conditions in superparamagnetic systems—with a functional calculus approach. This approach extends the Fokker-Planck equation (FPE) to magnetization dynamics under colored noise, moving beyond the usual Markovian approximations. By incorporating […]

We simulated the current-induced switching of magnetization of short vertical magnetic nanopillars as the free layer in a magnetic tunnel junction. Considering spin accumulation is crucial in such 3D elements, leading to an enhancement of the field-like torque, and the excitation of non-uniform FMR modes. 3D nanomagnetism is a fast-growing topic, motivated by fundamental physical […]

In this work, a consortium of physicists from SPINTEC and York addressed the challenge of nucleating quantitatively proven topological magnetic textures in compensated magnets with zero net magnetization. It paves the way for extending the study of topological spin textures beyond ferromagnets, into materials with intriguing electrodynamic properties, such as antiferromagnets and altermagnets.   Topologically […]

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 […]
