Anisotropy-Driven Anomalous Inverse Orbital Hall Effect in Fe Films
E. Santos, U. Borges, J. L. Costa +2
This study investigates the anomalous orbital effects in iron (Fe) films with strong uniaxial anisotropy, highlighting the interactions between spin and orbital currents. Using het…
Revealing the Dominance of the Orbital Hall Effect over Spin in Transition Metal Heterostructures
J. L. Costa, E. Santos, J. B. S. Mendes +1
We study inverse spin and orbital Hall effects in 19 transition metals using spin-pumping driven by ferromagnetic resonance. Spin-to-charge conversion was measured in YIG/X(5), whi…
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…
Exploring orbital-charge conversion mediated by interfaces with copper through spin-orbital pumping
E. Santos, J. E. Abrão, A. S. Vieira +3
We investigated how different materials affect the orbital-charge conversion in heterostructures with the naturally oxidized cooper capping layer. When we added a thin layer of $Cu…
