Anti-reflection coating design for metallic terahertz meta-materials
M. Pancaldi, R. Freeman, M. Hudl +4
We demonstrate a silicon-based, single-layer anti-reflection coating that suppresses the reflectivity of metals at near-infrared frequencies, enabling optical probing of nano-scale…
THz-driven demagnetization with Perpendicular Magnetic Anisotropy: Towards ultrafast ballistic switching
Debanjan Polley, Matteo Pancaldi, Matthias Hudl +3
We study THz-driven spin dynamics in thin CoPt films with perpendicular magnetic anisotropy. Femtosecond magneto-optical Kerr effect measurements show that demagnetization amplitud…
Local Terahertz Field Enhancement for Time-Resolved X-ray Diffraction
Michael Kozina, Matteo Pancaldi, Christian Bernhard +9
We report local field strength enhancement of single-cycle terahertz (THz) pulses in an ultrafast time-resolved x-ray diffraction experiment. We show that patterning the sample wit…
