Unidirectional orbital magnetoresistance in light metal/ferromagnet bilayers
Shilei Ding, Paul Noël, Gunasheel Kauwtilyaa Krishnaswamy +1
We report the observation of a unidirectional magnetoresistance (UMR) that originates from the nonequilibrium orbital momentum induced by an electric current in a naturally oxidize…
Spin-orbit torque switching of magnetic tunnel junctions for memory application
Viola Krizakova, Manu Perumkunnil, Sebastien Couet +2
Spin-orbit torques (SOT) provide a versatile tool to manipulate the magnetization of diverse classes of materials and devices using electric currents, leading to novel spintronic m…
Giant orbital Hall effect and orbital-to-spin conversion in 3d, 5d, and 4f metallic heterostructures
Giacomo Sala, Pietro Gambardella
The orbital Hall effect provides an alternative means to the spin Hall effect to convert a charge current into a flow of angular momentum. Recently, compelling signatures of orbita…
Control of field- and current-driven magnetic domain wall motion by exchange-bias in Cr2O3/Co/Pt trilayers
B. J. Jacot, S. Vèlez, P. Noël +4
We investigate the motion of magnetic domain walls driven by magnetic fields and current-driven spin-orbit torques in an exchange-biased system with perpendicular magnetization. We…
Engineering the spin-orbit torque efficiency and magnetic properties of Tb/Co ferrimagnetic multilayers by stacking order
Mickey Martini, Can Onur Avci, Silvia Tacchi +2
We measured the spin-orbit torques (SOTs), current-induced switching, and domain wall (DW) motion in synthetic ferrimagnets consisting of Co/Tb layers with differing stacking order…
Tailoring the switching efficiency of magnetic tunnel junctions by the fieldlike spin-orbit torque
Viola Krizakova, Marco Hoffmann, Vaishnavi Kateel +5
Current-induced spin-orbit torques provide a versatile tool for switching magnetic devices. In perpendicular magnets, the dampinglike component of the torque is the main driver of…
