Spin-voltage-driven efficient terahertz spin currents from the magnetic Weyl semimetals CoMnGa and CoMnAl
Genaro Bierhance, Anastasios Markou, Oliver Gueckstock +7
Magnetic Weyl semimetals are an emerging material class that combines magnetic order and a topologically non-trivial band structure. Here, we study ultrafast optically driven spin…
Transition of laser-induced terahertz spin currents from torque- to conduction-electron-mediated transport
Pilar Jiménez-Cavero, Oliver Gueckstock, Lukáš Nádvorník +16
Spin transport is crucial for future spintronic devices operating at bandwidths up to the terahertz (THz) range. In F|N thin-film stacks made of a ferro/ferrimagnetic layer F and a…
Atomic scale control of spin current transmission at interfaces
Mohamed Amine Wahada, Ersoy Sasioglu, Wolfgang Hoppe +7
Spin transmission at ferromagnet/heavy metal interfaces is of vital importance for many spintronic devices. Usually the spin current transmission is limited by the spin mixing cond…
Laser-induced terahertz spin transport in magnetic nanostructures arises from the same force as ultrafast demagnetization
R. Rouzegar, L. Brandt, L. Nadvornik +9
Laser-induced terahertz spin transport (TST) and ultrafast demagnetization (UDM) are central but so far disconnected phenomena in femtomagnetism and terahertz spintronics. Here, we…
