Spin-voltage-driven efficient terahertz spin currents from the magnetic Weyl semimetals Co${}_2$MnGa and Co${}_2$MnAl

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…
