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…
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 …
Magnetism and Spin Dynamics in Room-Temperature van der Waals Magnet FeGeTe
Laith Alahmed, Bhuwan Nepal, Juan Macy +12
Two-dimensional (2D) van der Waals (vdWs) materials have gathered a lot of attention recently. However, the majority of these materials have Curie temperatures that are well below…
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 domain wall substructures in Pt/Co/Ni/Ir multi-layers
Maxwell Li, Arjun Sapkota, Anish Rai +6
We examine the substructures of magnetic domain walls (DWs) in [Pt/(Co/Ni)/Ir] multi-layers using a combination of micromagnetic theory and Lorentz transmission electron mi…
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…
