abstract = {We show that electric currents are induced in inversion
asymmetric ferromagnets if the exchange splitting varies in
time after excitation by laser pulses. We interpret this
phenomenon as the magnetic variant of the inverse Edelstein
effect. Based on ab initio calculations we determine the
size of this effect in Co/Pt(111) and Mn/W(001) magnetic
bilayer systems and investigate its dependence on the
magnetization direction. The comparison of our theoretical
results to experiments measuring the THz signal emitted
after laser excitation suggests that ultrafast
demagnetization in 3d transition metal ferromagnets is
dominated by transverse spin fluctuations rather than by a
reduction of the exchange splitting.},
