Broadband spintronic detection of the absolute field strength of terahertz electromagnetic pulses
A. L. Chekhov, Y. Behovits, U. Martens +5
We demonstrate detection of broadband intense terahertz electromagnetic pulses by Zeeman-torque sampling (ZTS). Our approach is based on magneto-optic probing of the Zeeman torque…
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…
Magnetic domain scanning imaging using phase-sensitive THz-pulse detection
Finn-Frederik Stiewe, Tristan Winkel, Tobias Kleinke +8
In our study, we determine the alignment of magnetic domains in a CoFeB layer using THz radiation. We generate THz-pulses by fs-laser-pulses in magnetized CoFeB/Pt heterostructures…
Spintronic emitters for super-resolution in THz-spectral imaging
Finn-Frederik Stiewe, Tristan Winkel, Yuta Sasaki +9
THz-spectroscopy is an attractive imaging tool for scientific research, especially in life science, offering non-destructive interaction with matter due to its low photon energies.…
Interaction of fibrinogen-magnetic nanoparticle bioconjugates with integrin reconstituted into artificial membranes
Ulrike Martens, Una Janke, Sophie Moeller +3
Magnetic nanoparticles have a broad spectrum of biomedical applications including cell separation, diagnostics and therapy. One key issue is little explored: how do the engineered…
Frequency-independent terahertz anomalous Hall effect in DyCo, CoFe and GdFe thin films from DC to 40 THz
Tom S. Seifert, Ulrike Martens, Florin Radu +11
The anomalous Hall effect (AHE) is a fundamental spintronic charge-to-charge-current conversion phenomenon and closely related to spin-to-charge-current conversion by the spin Hall…
