abstract = {Coherent terahertz control of magnetization dynamics is an
area of current interest due toits great potential for the
realization of magnetization control on ultrafast timescales
in commercialdevices. Here we report on an experiment
realized at the THz beamline of the free electron laserFLASH
at DESY which offers a tunable terahertz radiation source
and spontaneously synchronizedfree-electron laser X-ray
pulses to resonantly probe the magnetization state of a
ferromagneticfilm. In this proof-of-principle experiment, we
have excited a thin Permalloy film at different
THzwavelengths and recorded the induced magnetization
dynamics with photons resonantly tuned to theNi M2,3
absorption edge. For THz pump pulses including higher orders
of the undulator source weobserved demagnetization dynamics,
which precise shape depended on the employed
fundamentalwavelength of the undulator source. Analyzing the
shape in detail, we can reconstruct the temporalprofile of
the electric field of the THz pump pulse. This offers a new
method for the realization of anin-situ terahertz beamline
diagnostic which will help researchers to adjust the pulse
characteristics asneeded, for example, for future studies of
THz induced coherent control of magnetization dynamics.},
