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…
Room-Temperature Intrinsic and Extrinsic Damping in Polycrystalline Fe Thin Films
Shuang Wu, David A. Smith, Prabandha Nakarmi +8
We examine room-temperature magnetic relaxation in polycrystalline Fe films. Out-of-plane ferromagnetic resonance (FMR) measurements reveal Gilbert damping parameters of …
Diffusive and Fluid-like Motion of Homochiral Domain Walls in Easy-Plane Magnetic Strips
David A. Smith, So Takei, Bella Brann +4
Propagation of easy-plane magnetic precession can enable more efficient spin transport than conventional spin waves. Such easy-plane spin transport is typically understood in terms…
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…
