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…
Damping enhancement in coherent ferrite/insulating-paramagnet bilayers
Jacob J. Wisser, Alexander J. Grutter, Dustin A. Gilbert +6
High-quality epitaxial ferrites, such as low-damping MgAl-ferrite (MAFO), are promising nanoscale building blocks for all-oxide heterostructures driven by pure spin current. Howeve…
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…
