Observation of terahertz spin-Hall magnetoresistance in the model system
P. KubaÅ¡ÄÃk, R. Schlitz, O. Gueckstock +17
We report the observation of spin Hall magnetoresistance (SMR) in prototypical bilayers of ferrimagnetic yttrium iron garnet (YIG) and platinum in the frequency range from 0 THz to…

Ultrafast electron heating as the dominant driving force of photoinduced terahertz spin currents
Reza Rouzegar, Pilar Jimenez-Cavero, Oliver Gueckstock +9
Ultrafast spintronics strongly relies on the generation, transport, manipulation and detection of terahertz spin currents (TSCs). In F|HM stacks consisting of a ferromagnetic layer…
