Transient Spin Density Wave Order Induced in the Normal State of BaFe2As2 by Coherent Lattice Oscillations
We trace the ultrafast dynamics of the spin density wave gap of the pnictide system BaFe2As2 probing resonantly with broadband multi-terahertz pulses. The photoexcitation in the low-temperature ground state leads to a fast suppression of the spin order followed by a slower recovery process. Surprisi...
