BaFe₂As₂ Investigated by Pump-Probe Spectroscopy under High Pressures

Fotev, I.; Aswartham, S.; Büchner, B.; Schneider, H.; Helm, M.; Pashkin, O.

We utilize pump-probe spectroscopy at pressures in the GPa range to measure the quasiparticle relaxation dynamics of BaFe₂As₂. The results reveal the pressure dependences of the spin-density wave condensate energy and the photoexcited quasiparticle lifetimes.
