Nanoscale imaging of current density with a single-spin magnetometer
K. Chang, A. Eichler, C. L. Degen
Charge transport in nanostructures and thin films is fundamental to many phenomena and processes in science and technology, ranging from quantum effects and electronic correlations…
Enhanced Non-Adiabaticity in Vortex Cores due to the Emergent Hall Effect
André Bisig, Collins Ashu Akosa, Jung-Hwan Moon +15
We present a combined theoretical and experimental study, investigating the origin of the enhanced non-adiabaticity of magnetic vortex cores. Scanning transmission X-ray microscopy…
Domain-wall induced large magnetoresistance effects at zero applied field in ballistic nanocontacts
Arndt von Bieren, Ajit K. Patra, Stephen Krzyk +5
We determine magnetoresistance effects in stable and clean permalloy nanocontacts of variable cross-section, fabricated by UHV deposition and in-situ electromigration. To ascertain…
Domain-wall depinning assisted by pure spin currents
D. Ilgaz, J. Nievendick, L. Heyne +11
We study the depinning of domain walls by pure diffusive spin currents in a nonlocal spin valve structure based on two ferromagnetic permalloy elements with copper as the nonmagnet…
In-Situ Contacting and Current-Injection into Samples in Photoemission Electron Microscopes
L. Heyne, M. Kläui, L. Le Guyader +1
Studying the interaction of spin-polarized currents with the magnetization configuration is of high interest due to the possible applications and the novel physics involved. High r…
Non-adiabatic spin torque investigated using thermally activated magnetic domain wall dynamics
M. Eltschka, M. Wötzel, J. Rhensius +7
Using transmission electron microscopy, we investigate the thermally activated motion of domain walls (DWs) between two positions in permalloy (Ni80Fe20) nanowires at room temperat…
