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…
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…
Current-induced spin-orbit field in permalloy interfaced with ultrathin Ti and Cu
Ryan W. Greening, David A. Smith, Youngmin Lim +5
How spin-orbit torques emerge from materials with weak spin-orbit coupling (e.g., light metals) is an open question in spintronics. Here, we report on a field-like spin-orbit torqu…
Conductivity-Like Gilbert Damping due to Intraband Scattering in Epitaxial Iron
Behrouz Khodadadi, Anish Rai, Arjun Sapkota +15
Confirming the origin of Gilbert damping by experiment has remained a challenge for many decades, even for simple ferromagnetic metals. In this Letter, we experimentally identify G…
Epitaxial thin films of pyrochlore iridate Bi_{2+x}Ir_{2-y}O_{7-delta}: structure, defects and transport properties
Wencao Yang, Yuantao Xie, Wenka Zhu +12
While pyrochlore iridate thin films are theoretically predicted to possess a variety of emergent topological properties, experimental verification of these predictions can be obstr…
