abstract = {The response of multidomain flux-closure structures (Landau
states) in micrometer-scale magnetic thin-film elements upon
fast magnetic field pulses leads to the excitation of
magnetic eigenmodes and to short-lived domain patterns that
do not occur in quasi-static remagnetisation. Such transient
spatio-temporal patterns and particular detail features are
discussed. Examples are presented for perm-alloy platelets
of various shapes and sizes. Dynamic series of domain
patterns with variable delay between field pulse and photon
pulse (synchrotron radiation) have been taken using
stroboscopic XMCD-PEEM. Precessional remagnetisation starts
at the domain boundaries. The damped precessional motion
propagates into the domains magnetised perpendicular to the
field Pulse. Further, an apparent dynamical broadening of
domain boundaries, the formation of transient vortices and
domain walls as well as the fast formation of blocking
patterns are discussed. An important feature is the action
of the demagnetising field that develops via the damped
precessional motion of the magnetisation on the nanosecond
time scale. The effective field is constituted by the sum of
the instantaneous external pulse field and the delayed
response of the demagnetising field. (c) 2006 Published by
