Spin-to-charge-current conversion in altermagnetic candidate RuO${}_2$ 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${}_2$. We perform a quantit…
