Spin-torque induced wall motion in perpendicularly magnetized discs: ballistic versus oscillatory behavior
Paul Bouquin, Joo-Von Kim, Olivier Bultynck +4
We use time-resolved measurement and modeling to study the spin-torque induced motion of a domain wall in perpendicular anisotropy magnets. In disc of diameters between 70 and 100…
Oxide spin-orbitronics: spin-charge interconversion and topological spin textures
Felix Trier, Paul Noël, Joo-Von Kim +3
Quantum oxide materials possess a vast range of properties stemming from the interplay between the lattice, charge, spin and orbital degrees of freedom, in which electron correlati…
Stochastic processes in magnetization reversal involving domain wall motion in magnetic memory elements
Paul Bouquin, Joo-Von Kim, Olivier Bultynck +4
We show experimentally through time-resolved conductance measurements that magnetization reversal through domain wall motion in sub-100 nm diameter magnetic tunnel junctions is dom…
Material developments and domain wall based nanosecond-scale switching process in perpendicularly magnetized STT-MRAM cells
Thibaut Devolder, Joo-Von Kim, J. Swerts +6
We investigate the Gilbert damping and the magnetization switching of perpendicularly magnetized FeCoB-based free layers embedded in tunnel junctions adequate for spin-torque opera…
Current-driven skyrmion dynamics in disordered films
Joo-Von Kim, Myoung-Woo Yoo
A theoretical study of the current-driven dynamics of magnetic skyrmions in disordered perpendicularly-magnetized ultrathin films is presented. The disorder is simulated as a granu…
Spin wave power flow and caustics in ultrathin ferromagnets with the Dzyaloshinskii-Moriya interaction
Joo-Von Kim, Robert L. Stamps, Robert E. Camley
The Dzyaloshinskii-Moriya interaction in ultrathin ferromagnets can result in nonreciprocal propagation of spin waves. We examine theoretically how spin wave power flow is influenc…
