Position: We are opening a postdoctoral research position to perform spin-wave spectroscopy on a home-built NV-center microscope. The scientific goal is to exploit the exquisite sensitivity of the instrument to map the spatio-temporal profile of otherwise hidden azimuthal modes. Our long-term objective is to develop a high-performance orbital-angular-momentum transducer between photons, magnons, and phonons, using […]

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 […]

Quantum spintronic devices with non-Hermitian topology Multi-terminal quantum Hall devices with non-Hermitian topology are highly-sensitive cryogenics sensors with quantized properties robust against imperfections. In collaboration with RIKEN-CEMS & IFW Dresden, we have shown the record sensitivity of such quantum sensors built from magnetic topological insulators, operating at higher temperatures than devices solely based on the […]

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 […]
