Open PostDoctoral position on Spin-Wave Spectroscopy by a Single Paramagnetic Center

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 […]

Opening Postdoctoral Position: New Paradigms in Spintronic Fluctuations

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 […]

Low-Noise Nanoscale Vortex Sensor for Out-of-Plane Magnetic Field Detection

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 in cylindrical magnetic conduits: from theory to experiment

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. […]

E pur si muove!*

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 […]
