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…
Influence of the presence of multiple resonances on material parameter determination using broadband ferromagnetic resonance spectroscopy
Prabandha Nakarmi, Tim Mewes
The influence of the presence of multiple resonances in ferromagnetic resonance spectra on extracted material parameters is investigated using numerical simulations. Our results sh…
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…
Enhancement in Thermally Generated Spin Voltage at Pd/NiFeO Interfaces by the Growth on Lattice-Matched Substrates
A. Rastogi, Z. Li, A. V. Singh +15
Efficient spin injection from epitaxial ferrimagnetic NiFeO thin films into a Pd layer is demonstrated via spin Seebeck effect measurements in the longitudinal geometry. Th…
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…
