Probing the Spin-Momentum Locking in Rashba Surfaces via Spin Current
J. E. Abrão, E. Gomes da Silva, G. Rodrigues-Junior +2
In this work, we explore the intriguing spin-momentum locking phenomenon within the Rashba states of antimony (Sb) films. By combining spin pumping with the flow of an external cha…
Anomalous Spin and Orbital Hall Phenomena in Antiferromagnetic Systems
J. E. Abrão, E. Santos, J. L. Costa +3
We investigate anomalous spin and orbital Hall phenomena in antiferromagnetic (AF) materials via orbital pumping experiments. Conducting spin and orbital pumping experiments on YIG…
Negative orbital Hall effect in Germanium
E. Santos, J. E. Abrao, J. L. Costa +3
Our investigation reveals a groundbreaking discovery of a negative inverse orbital Hall effect (IOHE) in Ge thin films. We employed the innovative orbital pumping technique where s…
Bulk and Interface Effects Based on Rashba-Like States in Ti and Ru Nanoscale-Thick Films: Implications for Orbital-Charge Conversion in Spintronic Devices
Eduardo S. Santos, José E. Abrão, Jefferson L. Costa +8
In this work, employing spin-pumping techniques driven by both ferromagnetic resonance (SP-FMR) and longitudinal spin Seebeck effect (LSSE) to manipulate and direct observe orbital…
