Spin-wave propagation at low temperatures in YIG thin films on YSGG substrates
José Elias Abrão, Daan Weltens, Rhodri Mansell +2
The use of spin waves in magnetic thin films at cryogenic temperatures has long been hindered by the lack of a suitable material platform. Yttrium iron garnet (YIG) is the leading…
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…
Experimental verification of the inverse Anomalous spin Hall effect with perpendicular magnetic anisotropy Materials
J. E. Abrão, A. R. Rodrigues, H. F. Ding +2
In this work, the spin pumping technique was employed to investigate the anomalous inverse spin Hall effect in BIG/NiO/Fe samples where BIG[(Bi,Tm)3(Fe,Ga)5O12] exhibits perpendicu…
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…
Inverse Orbital Torque via Spin-Orbital Entangled States
E. Santos, J. E. Abrão, Dongwook Go +4
While current-induced torque by orbital current has been experimentally found in various structures, evidence for its reciprocity has been missing so far. Here, we report experimen…
Unveiling the polarity of the spin-to-charge current conversion in
J. B. S. Mendes, M. Gamino, R. O. Cunha +3
We report an investigation of the spin- to charge-current conversion in sputter-deposited films of topological insulator onto single crystalline layers of YIG $(Y_{3}F…
