Project description
Capturing spin current dynamics in real time
Spintronic processes happen on extremely tiny scales both in space and time, making them very difficult to observe. Supported by the Marie Skłodowska-Curie Actions programme, the TeraSCN project aims to develop an innovative tool called spintronic terahertz emission nanoscopy that combines terahertz emission spectroscopy and near-field optical microscopy. The proposed platform will allow researchers to capture detailed images of spin current dynamics with nanometre-level precision and femtosecond-level speed. Researchers will study how spin currents behave around domain walls and defects. They will also image how spin currents created by light flow within magnetic skyrmions and investigate how spins and magnons lose energy over time. These experiments will create the first-ever ‘movies’ showing how spin currents behave in real time at their natural scales.
Objective
TeraSCN will establish spintronic terahertz emission nanoscopy (STEN), the first European tabletop platform capable of imaging spin current dynamics with nanometer spatial and femtosecond temporal resolution, the natural time and length scales of spintronic processes. This development is achieved by combining spintronic terahertz emission spectroscopy with scattering-type scanning near-field optical microscopy (s-SNOM). I will adapt and optimize a commercial s-SNOM for STEN operation and determine its instrument response function, enabling extraction of spin current dynamics from measured terahertz signals. Unlike synchrotron-based X-ray techniques (e.g. XMCD-PEEM), STEN provides superior spatiotemporal access at much lower cost and with year-round availability, ensuring broad adoption across European laboratories.
With this capability, TeraSCN will address fundamental open questions in spintronics. I will resolve spin-current dynamics at domain walls, defects, and pinning sites to identify their transport mechanisms (ballistic, diffusive, tunneling). I will also image light-induced terahertz spin currents in magnetic skyrmions at previously inaccessible resolution, probing spin and magnon relaxation and experimentally testing the predicted skyrmion topological terahertz resonance. These experiments will deliver the first direct movies of spin-current dynamics at their natural scales.
TeraSCN will have both scientific and technological impact. Scientifically, it will provide a powerful tool for uncovering fundamental spin physics. Technologically, by elucidating how defects and nanoscale textures govern spin-current efficiency, STEN will accelerate the development of next-generation spintronic technologies, including racetrack memories, spin-based logic, and neuromorphic devices.
