Facilitating electrical and laser-induced skyrmion nucleation with a dipolar-field enhanced effective DMI
Mark C. H. de Jong, Dinar Khusyainov, Julian Hintermayr +6
We demonstrate experimentally how the nucleation of skyrmions in an Ir, Co, and Pt based magnetic multilayer is affected by introducing a layer dependent sign for the Dzyaloshinski…
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…
Demonstration of on-chip all-optical switching of magnetization in integrated photonics
Pingzhi Li, Gijs W. A. Simons, Tianyu Zhang +7
Ultrafast all-optical magnetization switching (AOS) holds great promise for nextgeneration spintronic memory and hybrid spintronic-photonic systems. However, most implementations t…
A refinement of the Lorentz local field expression with impact on the Clausius-Mossotti and Lorentz-Lorenz models
Jeroen van Duivenbode, Anne-Jans Faber, Reinoud Lavrijsen
In the 19th century Mossotti and Clausius developed an expression linking the electrical permittivity of a dielectric to the product of molecular polarizability and number density.…
AFM Cantilever Magnetometry for Measuring Femto-Nm Torques Generated by Single Magnetic Particles for Cell Actuation
Maria V. Efremova, Lotte Boer, Laurenz Edelmann +4
Particles with high anisotropy in their magnetic properties and shape are of increasing interest for mechanobiology, where transducing a remotely applied magnetic field vector to a…
