abstract = {This thesis describes the investigation of the field
dependent magnetic spin structure of an
antiferromagnetically (AF) coupled Fe/Cr heterostructure
sandwiched between a hardmagnetic FePt buffer layer and a
softmagnetic Fe top layer. The depth-resolved experimental
studies of this system were performed via Magneto-optical
Kerr effect (MOKE), Vibrating Sample Magnetometry (VSM) and
various measuring methods based on nuclear resonant
scattering (NRS) technique. Nucleation and evolution of the
magnetic spiral structure in the AF coupled Fe/Cr multilayer
structure in an azimuthally rotating external magnetic field
were observed using NRS. During the experiment a number of
time-dependent magnetic side effects (magnetic after-effect,
domain-wall creep effect) caused by the non-ideal structure
of a real sample were observed and later explained. Creation
of the magnetic spiral structure in rotating external
magnetic field was simulated using a one-dimensional
micromagnetic model.The cross-sectional magnetic x-ray
diffraction technique was conceived and is theoretically
described in the present work. This method allows to
determine the magnetization state of an individual layer in
the magnetic heterostructure. It is also applicable in
studies of the magnetic structure of tiny samples where
conventional x-ray reflectometry fails.},
