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 […]

Recruiting consultant in crystal growth by liquid phase epitaxy Context: In 2025, the spin-insulatronics team of SPINTEC was awarded an exploratory grant from the PEPR SPIN program to develop new types of ultra-high-fidelity optomechanical modulators operating at frequencies in the GHz range and incorporating ferrimagnetic materials into optical components. The project is named MAGISTRAL for […]

On Wednesday January 21th, at 14:00, Maxime CULOT (SPINTEC) will defend his PhD thesis entitled : Memristive switching in GeTe-based ferroelectric Schottky diodes for neuromorphic computing Place : IRIG/SPINTEC, CEA Building 10.05, auditorium 445 (presential access to the conference room at CEA in Grenoble requires an entry authorization, request it before January 10th to admin.spintec@cea.fr) […]

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) […]

On Monday, February 3th 2024, we have the pleasure to welcome in SPINTEC Grégoire De Loubens from CEA Iramis. He will give us a seminar at 14:00 entitled : Nonlinear interactions between parametrically excited spin-wave modes in a YIG microdisk Place : IRIG/SPINTEC, auditorium 445 CEA Building 10.05 (presential access to the conference room at […]

Building a ubiquitous high-speed Internet from anywhere in the world or a long-range quantum network are two technological challenges that both require the development of a phase-sensitive transducer that can interconvert information from microwave frequencies at which wireless networks or quantum computers operate to optical frequencies, the optimal telecommunications band for long-distance information exchange. However, […]

On Monday November 04th 2024, we have the pleasure to welcome in SPINTEC Clément Pellet-Mary from the University of Basel. He will give us a seminar at 14:00 entitled : Engineering anti-ferromagnetic domains in atomically thin magnet Place : IRIG/SPINTEC, auditorium 445 CEA Building 10.05 (access to CEA requires an entry authorization. Request it before […]

Spin electronics applies to a wide range of materials: metals, where spin is transported by electrons, but also magnetic insulators, where spin is transported by magnons. The latter are of interest because in certain insulators, such as yttrium iron garnet (YIG), it is predicted that one could reach a state of superfluidity, i.e. spin transport […]
