Large-Amplitude, Easy-Plane Spin-Orbit Torque Oscillators Driven by Out-of-Plane Spin Current: A Micromagnetic Study

Daniel Kubler, David A. Smith, Tommy Nguyen +3

Spin torque oscillators are spintronic devices that generate a periodic output signal from a non-periodic input, making them promising candidates for applications like microwave co…

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…

Observation of Coherently Coupled Cation Spin Dynamics in an Insulating Ferrimagnetic Oxide

C. Klewe, P. Shafer, J. E. Shoup +11

Many technologically useful magnetic oxides are ferrimagnetic insulators, which consist of chemically distinct cations. Here, we examine the spin dynamics of different magnetic cat…

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 …
