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.…
Thermally induced all-optical ferromagnetic resonance in thin YIG films
E. Schmoranzerová, J. Kimák, R. Schlitz +10
All-optical ferromagnetic resonance (AO-FMR) is a powerful tool for local detection of micromagnetic parameters, such as magnetic anisotropy, Gilbert damping or spin stiffness. In…
Ultrafast demagnetization of iron induced by optical vs terahertz pulses
A. L. Chekhov, Y. Behovits, J. J. F. Heitz +7
We study ultrafast magnetization quenching of ferromagnetic iron following excitation by an optical vs a terahertz pump pulse. While the optical pump (photon energy of 3.1 eV) indu…
