- Quantum spintronic devices with non-Hermitian topology (September 15th, 2026)
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 ... - Dzyaloshinskii-Moriya interaction chirality reversal with ferromagnetic thickness (September 04th, 2026)
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 ... - High-temperature ferromagnetism in 2D (August 28th, 2026)
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 ... - Spin waves in cylindrical magnetic conduits: from theory to experiment (July 27th, 2026)
Spin waves are propagating fundamental excitations of magnetic systems, also carrying promises for low-power logic and data transfer. We report the measurement of thermal spin-wave spectra in single cylindrical nanowires, and their quantitative analysis as ... - E pur si muove!* (July 23rd, 2026)
Angular momentum (AM) is the conserved quantity associated with rotational invariance. Harnessing its orbital component in axi-symmetric sample is often challenging. Interestingly, we show that azimuthal spin waves in normally magnetized disks are largely immune ... - Magnetic vortex micro-disks dynamics in viscoelastic environments (July 15th, 2026)
Magnetically driven microparticles provide a versatile platform for probing and manipulating biological systems. Yet the physical framework governing their actuation in complex environments remains only partially explored. In this work, we introduced a simplified model ... - Pulse Shaping Suppresses Intrinsic Back-Switching in SOT-MRAM (July 05th, 2026)
Spin–orbit-torque (SOT) MRAM writing exhibits an unusual current dependence: at high current amplitudes, the write probability can drop to zero or even oscillate as the current increases. In collaboration with Antaios, we showed that this ... - Low-Noise Nanoscale Vortex Sensor for Out-of-Plane Magnetic Field Detection (June 30th, 2026)
Magnetic field sensors are widely used for contactless current measurement, as well as in the automotive and robotics industries for position encoding. Vortex sensors are particularly attractive for these applications because of their linear response ... - A one-way sound transmitter (December 08th, 2025)
Magnetism is well-known to inherently break time-reversal symmetry; for example, the magnetization precesses in a single (counter-clockwise) direction around its equilibrium axis. By integrating a magnetic thin film onto a piezoelectric substrate, enabling phonons to ... - Physics of current-induced switching in 3D nanopillars (November 03rd, 2025)
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 ... - Controlling effective anisotropy for efficient switching at cryogenic temperature (October 24th, 2025)
The field of cryoelectronics holds promise for high-performance computing applications, particularly within the realm of quantum computing. Recent advances in quantum computing systems have spurred the investigation of various technologies suitable for cryogenic environments.

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 ... - Nanosecond stochastic operation in perpendicular superparamagnetic tunnel junctions (September 08th, 2025)
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 ...
