Vertically Graded Fe-Ni Alloys with Low Damping and a Sizeable Spin-Orbit Torque
Rachel E. Maizel, Shuang Wu, Purnima P. Balakrishnan +13
Energy-efficient spintronic devices require a large spin-orbit torque (SOT) and low damping to excite magnetic precession. In conventional devices with heavy-metal/ferromagnet bila…
Suppression of Spin Pumping at Metal Interfaces
Youngmin Lim, Bhuwan Nepal, David A. Smith +15
An electrically conductive metal typically transmits or absorbs a spin current. Here, we report on evidence that interfacing two metal thin films can suppress spin transmission and…
Absorption of Transverse Spin Current in Ferromagnetic NiCu: Dominance of Bulk Dephasing over Spin-Flip Scattering
Youngmin Lim, Shuang Wu, David A. Smith +3
In ferromagnetic metals, transverse spin currents are thought to be absorbed via dephasing -- i.e., destructive interference of spins precessing about the strong exchange field. Ye…
Sub-Nanosecond Spin-Transfer Torque in an Ensemble of Superparamagnetic-Like Nanomagnets
Satoru Emori, Christoph Klewe, Jan-Michael Schmalhorst +14
Spin currents can exert spin-transfer torques on magnetic systems even in the limit of vanishingly small net magnetization, as is the case for antiferromagnets. Here, we experiment…
Magnetic Damping in Epitaxial Fe Alloyed with Vanadium and Aluminum
David A. Smith, Anish Rai, Youngmin Lim +12
To develop low-moment, low-damping metallic ferromagnets for power-efficient spintronic devices, it is crucial to understand how magnetic relaxation is impacted by the addition of…
Dephasing of Transverse Spin Current in Ferrimagnetic Alloys
Youngmin Lim, Behrouz Khodadadi, Jie-Fang Li +3
It has been predicted that transverse spin current can propagate coherently (without dephasing) over a long distance in antiferromagnetically ordered metals. Here, we estimate the…
