Effective field analysis using the full angular spin-orbit torque magnetometry dependence
Tomek Schulz, Kyujoon Lee, Benjamin Krüger +7
Spin-orbit torques promise ultra-efficient magnetization switching used for advanced devices based on emergent quasi-particles such as domain walls and skyrmions. Recently, the spi…
Modification of Dzyaloshinskii-Moriya interaction stabilized domain wall chirality by driving currents
G. V. Karnad, F. Freimuth, E. Martinez +7
We measure and analyze the chirality of the Dzyaloshinskii-Moriya interaction (DMI) stabilized spin textures in multilayers of Ta/CoFeB/MgO. The effective DMI…
Study of energetics of 360° domain walls through annihilation
G. V. Karnad, E. Martinez, M. Voto +4
The Dzyaloshinskii-Moriya interaction (DMI) causes domain walls in perpendicular magnetized systems to adopt a homochiral configuration by winding in the same direction for both Up…
Role of phonon skew scattering in the spin Hall effect of platinum
G. V. Karnad, C. Gorini, K. Lee +11
We measure and analyze the effective spin Hall angle of platinum in the low residual resistivity regime by second harmonic measurements of the spin-orbit torques for a multilayer o…
Ferromagnetic layer thickness dependence of the Dzyaloshinskii-Moriya interaction and spin-orbit torques in Pt\Co\AlOx
Roberto Lo Conte, Gurucharan V. Karnad, Eduardo Martinez +9
We report the thickness dependence of Dzyaloshinskii-Moriya interaction (DMI) and spin-orbit torques (SOTs) in Pt\Co(t)\AlOx, studied by current-induced domain wall (DW) motion and…
Spin-orbit torques for current parallel and perpendicular to a domain wall
Tomek Schulz, Oscar Alejos, Eduardo Martinez +10
We report field- and current-induced domain wall (DW) depinning experiments in Ta/Co20Fe60B20/MgO nanowires through a Hall cross geometry. While purely field-induced depinning show…
Interfacial Dzyaloshinskii-Moriya interaction in Ta\Co20Fe60B20\MgO nanowires
R. Lo Conte, E. Martinez, A. Hrabec +10
We report current-induced domain wall motion (CIDWM) in Ta\Co20Fe60B20\MgO nanowires. Domain walls are observed to move against the electron flow when no magnetic field is applied,…
Origin of the spin Seebeck effect probed by temperature dependent measurements in GdFeO
Stephan Geprägs, Andreas Kehlberger, Tomek Schulz +10
We probe the spin Seebeck effect in GdFeO/Pt hybrid structures as a function of temperature and observe two sign changes of the spin Seebeck signal with decreasi…
Spin-orbit torque-driven magnetization switching and thermal effects studied in Ta\CoFeB\MgO nanowires
R. Lo Conte, A. Hrabec, A. P. Mihai +5
We demonstrate magnetization switching in out-of-plane magnetized Ta\CoFeB\MgO nanowires by current pulse injection along the nanowires, both with and without a constant and unifor…
