Comparative Analysis of THz Signal Emission from SiO/CoFeB/Metal Heterostructures: Wideband and High-Frequency THz Signal Advantage of PtBi-based Emitter
Tristan Joachim Winkel, Tahereh Sadat Parvini, Finn-Frederik Stiewe +3
Spintronic THz emitters have attracted much attention due to their desirable properties, such as affordability, ultra-wideband capability, high efficiency, and tunable polarization…
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.…
