Terahertz magneto-photocurrents in the topological insulator BiSe probe its topological surface states
Chihun In, Genaro Bierhance, Deepti Jain +5
We study ultrafast magneto-photocurrents in a three-dimensional topological insulator. For this purpose, we excite (InBi)Se thin films with a femtosecond laser…
Broad-band THz emission by Spin-to-Charge Conversion in Topological Material -- Ferromagnet Heterostructures
Xingyue Han, Xiong Yao, Tilak Ram Thapaliya +10
Terahertz spintronic devices combine ultrafast operation with low power consumption, making them strong candidates for next-generation memory technologies. In this study, we use ti…
Femtosecond photocurrents by the Dresselhaus bulk spin-galvanic effect in an inversion-asymmetric ferromagnet
Junwei Tong, Zdenek Kaspar, Afnan Alostaz +18
We study ultrafast photocurrents in thin films of a model ferromagnetic metal with broken bulk inversion symmetry, the half-metallic Heusler compound NiMnSb, following excitation w…
Terahertz time-domain signatures of the inverse Edelstein effect in topological-insulator|ferromagnet heterostructures
Genaro Bierhance, Chihun In, Enzo Rongione +14
Three-dimensional topological insulators possess topologically protected surface states with spin-momentum locking, which enable spin-charge-current interconversion (SCI) by the in…
Tunable ultrabroadband hybrid THz emitter combining a spintronic THz source and a GaSe crystal
Afnan Alostaz, Oliver Gueckstock, Jungwei Tong +4
Linear terahertz time-domain spectroscopy (THz-TDS) is a sensitive probe for material characterization including thickness measurements of thin layers. These applications criticall…
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…
