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 […]

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. Among these technologies, spintronic memory elements have received significant attention due to their potential for minimal energy consumption. Specifically, these elements […]

In this work, a consortium of physicists from SPINTEC and York addressed the challenge of nucleating quantitatively proven topological magnetic textures in compensated magnets with zero net magnetization. It paves the way for extending the study of topological spin textures beyond ferromagnets, into materials with intriguing electrodynamic properties, such as antiferromagnets and altermagnets.   Topologically […]
