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…
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…
Identification and characterization of various plastics using THz-spectroscopy
Tobias Kleinke, Finn-Frederik Stiewe, Tristan Winkel +5
THz spectroscopy has reached imaging capability with a spatial resolution of a few micrometres. This property enables measurements and imaging of biological samples like cells. THz…
Circular photogalvanic effects in topological insulator/ferromagnet hybrid structures
T. Schumann, T. Kleinke, L. Braun +12
We study laser driven spin-current effects at ferromagnet/topological-insulator interfaces by two complementary experimental approaches. The DC photocurrent is studied in ferromagn…
Giant quadratic magneto-optical response of thin YIG films for sensitive magnetometric experiments
E. Schmoranzerová, T. Ostatnický, J. Kimák +10
We report on observation of a magneto-optical effect quadratic in magnetization (Cotton-Mouton effect) in 50 nm thick layer of Yttrium-Iron Garnet (YIG). By a combined theoretical…
Observation of multi-skyrmion objects created by size and density control in Ta/CoFeB/MgO films
Christian Denker, Sören Nielsen, Enno Lage +7
Magnetic skyrmions are chiral spin textures with a nontrivial topology that offer a potential for future magnetic memory and storage devices. The controlled formation and adjustmen…
