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 and weak temperature dependence. Conventional vortex sensors are sensitive to magnetic fields applied in the sensor plane. We developed a […]

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 modes with a radial and azimuthal index. This opens the route for more elaborate investigations including generation, manipulation and detection. […]

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 […]

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 to imperfections that would otherwise prevent the wavefront from orbiting around the disk. * “And yet it moves!” is the […]

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 describing the magneto-mechanical response of such particles embedded in viscoelastic media under varying magnetic fields. For several years now, the […]

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 behavior originates from an intrinsic, largely deterministic back-switching mechanism, and we demonstrated that tailoring the pulse fall time significantly widens […]

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 hybridize with magnons, we show that this intrinsic nonreciprocity can be transferred to surface acoustic waves. Surface acoustic wave (SAW) […]

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 […]

Recent advances in quantum computing systems have spurred the investigation of various technologies suitable for cryogenic environments. Among these technologies, spintronic memory elements have received significant attention due to their potential for minimal energy consumption. Specifically, these elements […]
