Nonlinear terahertz Néel spin-orbit torques in antiferromagnetic MnAu
Yannic Behovits, Alexander L. Chekhov, Stanislav Yu. Bodnar +8
Antiferromagnets have large potential for ultrafast coherent switching of magnetic order with minimum heat dissipation. In novel materials such as MnAu and CuMnAs, electric rat…
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…
Surface plasmon-enhanced photo-magnetic excitation of spin dynamics in Au/YIG:Co magneto-plasmonic crystals
Artsiom Kazlou, Alexander L. Chekhov, Alexander I. Stognij +2
We report strong amplification of photo-magnetic spin precession in Co-doped YIG employing a surface plasmon excitation in a metal-dielectric magneto-plasmonic crystal. Plasmonic e…
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…
Ultrafast transport and relaxation of hot plasmonic electrons in metal-dielectric heterostructures
Ilya Razdolski, Alexander L. Chekhov, Alexander I. Stognij +1
We analyze ultrafast electron dynamics in the time domain upon optical excitation of propagating surface plasmon-polaritons (SPs) in metal-dielectric heterostructures. Developing a…
