Spin Inertia as a Driver of Chaotic and High-Speed Ferromagnetic Domain Walls
A. L. Bassant, Y. M. J. Ohlsen, M. Cherkasskii +2
Ferromagnetic domain walls -transitional regions between magnetic domains- are an essential ingredient for racetrack memory, a device concept that promises to deliver faster and mo…
Fluctuations of the inverted magnetic state and how to sense them
Anna-Luisa E. Römling, Artim L. Bassant, Rembert A. Duine
Magnons are the low-energy excitations of magnetically ordered materials. While the magnetic moment of a ferromagnet aligns with an applied magnetic field, it has been experimental…
Direct Observation of Antimagnons with Inverted Dispersion
Hanchen Wang, Junfeng Hu, Wenjie Song +14
We report direct spectroscopic evidence of antimagnons, i.e., negative-energy spin waves identified by their signature inverted dispersion and left-handed precession with Brillouin…
Controlling Spin-Waves by Inhomogeneous Spin-Transfer Torques
Lorenzo Gnoatto, Jean F. O. da Silva, Artim L. Bassant +4
We investigate the interplay between spin currents and spin waves in nanofabricated Permalloy waveguides with geometrical constrictions. Using propagating spin-wave spectroscopy, m…
Current-Induced Modulation of Spin-Wave Propagation in a Y-Junction via Transverse Spin-Transfer Torque
Lorenzo Gnoatto, Rai M. Menezes, Artim L. Bassant +3
We report the transverse control of spin-wave propagation in the configuration where the spin-wave wavevector k is perpendicular to the charge-current density J. Building on theore…
Thermal Spin Waves from Accelerating Domain Walls via the Unruh Effect
A. L. Bassant, R. A. Duine
We consider a wire consisting of a conducting ferromagnetic layer and an insulating antiferromagnetic layer that are coupled. The ferromagnet hosts a domain wall, which is dynamica…
Observation and Control of Chiral Spin Frustration in BiYIG Thin Films
Jinlong Wang, Hanchen Wang, Zhewen Xu +17
Chiral interactions within magnetic layers stabilize the formation of noncollinear spin textures, which can be leveraged to design devices with tailored magnetization dynamics. Her…
Investigating the Interplay between Spin-Polarization and Magnetic Damping in for Magnonics Applications
Lorenzo Gnoatto, Thomas Molier, Jelte J. Lamberts +4
For magnonics and spintronics applications, the spin polarization () of a transport current and the magnetic damping () play a crucial role, e.g. for magnetization dynamics a…
Phonon Amplification via Magnetoelastic Klein Scattering
A. L. Bassant, M. F. van Willigen, R. A. Duine
Materials exhibit various wave-like excitations, among which phonons (lattice vibrations) and magnons (oscillations in ferromagnetic ordering) hold significant promise for future n…
Entangled magnon-pair generation in a driven synthetic antiferromagnet
Artim L. Bassant, Mexx E. Y. Regout, Joren S. Harms +1
Understanding, manipulating, and using magnons - the quanta of spin waves - for energy-efficient applications is one of the primary goals of magnonics. In this paper, we consider a…
