Terahertz spin-current transparency through rough interfaces
Jiří Jechumtál, Jakub Zázvorka, Ondřej Novák +8
Spin transport across interfaces is critical for spintronic devices, yet remains difficult to probe on ultrafast timescales. We use terahertz emission spectroscopy on Co|Pt heteros…

Spin-to-charge-current conversion in altermagnetic candidate RuO probed by terahertz emission spectroscopy
J. Jechumtál, O. Gueckstock, K. Jasenský +19
Using the THz emission spectroscopy, we investigate ultrafast spin-to-charge current conversion in epitaxial thin films of the altermagnetic candidate RuO. We perform a quantit…

Stress-induced Martensitic transformation in epitaxial Ni-Mn-Ga thin films and its correlation to optical and magneto-optical properties
M. Makeš, J. Zázvorka, M. Hubert +5
The optical and magneto-optical properties of thin epitaxial Ni-Mn-Ga films, with thicknesses ranging from 8 to 160 nm, were investigated across the spectral range of 0.7-6.4 eV. T…
