We will interconvert orbital, spin and charge currents using magnetic heterostructures involving both light and heavy metals. The cooperation of spin-orbit coupling and orbital currents will generate unprecedented increased torques acting on the magnetization. Materials investigations and complementary theoretical models will be developed to quantitatively evaluate the role of orbital effects on these processes.
We will experimentally demonstrate charge-neutral orbital currents and orbital accumulations in non-magnetic heterostructures involving light metals only. Phenomenological and realistic models for orbital transport will be developed to understand semiclassical orbital diffusion, injection and relaxation.
Optical beams with spin and orbital angular momenta will be developed and implemented to probe the presence of non-equilibrium orbital densities, inject pure orbital currents and polarizations, and realize ultrafast orbital-to-charge conversion.
Our ambition is to design, fabricate and test a collection of emblematic devices in ICTs relying on the physics of orbital currents that could be key elements for the diverse anticipated applications e.g., sensors, THz devices, rf nano-oscillators, transistors for logic and a flagship non-volative memory.
