Summary
Limiting power consumption for massive data while increasing data processing speed and transfer rates requires the development of innovative architectures for logic, memory, and hyper frequencies applications. Spintronics brings some answers proposing solutions based on spin-orbit coupling. However, there is still a need to further reduce power consumption, simplify memory architectures, and close the THz gap. I propose unconventional experiments to develop magnetic-based platforms towards sub-THz spin current generation without the use of laser sources and gain access to the study of magnetic materials with high resonance frequencies.
I formulate here new challenges presenting cutting-edge concepts involving spin-orbit coupling in magnetic alloys and compounds with magnetic Rashba interfaces. These will allow exploring and exploiting the ultra-high harmonics generation of spin currents, spin-orbitronics signals, in the sub-THz domain by tuning the ferromagnetic exchange and Rashba splitting.
Based on these innovative concepts, MAGNETALLIEN has a twofold objective: i) to demonstrate that magnetic alloys and compounds, such as amorphous ferrimagnets and magnetic epitaxial Heusler, that possess strong spin-orbit coupling will lead to a new platform for efficient spin current self-production and, ii) will lead to the production of ultra-high harmonics spin pumping voltage up to tens or hundreds of GHz enabling various uses in new spin-orbitronics experiments.
MAGNETALLIEN project will generate knowledge in spin current self-production and self-torque in magnetic alloys and compounds that will allow making decisive progress for less-energy-consuming architectures. Although of fundamental nature, demonstrating the existence of ultra-high harmonics signal which exploitation in innovative devices for spin-orbitronics goes far beyond the state of the art, this project will open new avenues and perspectives to tackle in a disruptive way all-electric sub-THz domain.
