abstract = {Chiral magnetic structures in single crystals and thin film
structures probed by polarization-analyzedSmall Angle
Neutron Scattering (SANS) $\&$ Grazing-Incidence-SANS are
often connected to complexanalysis procedures and require
the development of individual magnetic models. Additionally,
precisedata-reduction protocols are needed to distinguish
sample scattering from instrumentationaleffects. The more
involved the different interactions in one sample system,
the more care has tobe taken for a comprehensive
understanding as function of, e.g., magnetic field, electric
field, temperature,and further parameter sets. The key to a
broad understanding then can be given by thecomparison of
various analysis methods.Here, I will provide two examples
on the complexity of magnetic (GI-)SANS data analysis on
differentmaterials: (i) a ferromagnetic/superconducting thin
film with temperature dependent chiralmagnetic domain walls,
and (ii) a magnetoelectric single crystal with chiral
magnetic phases dependingon temperature, magnetic, and
electric field. For study (i) we will compare
polarization-analyzedGISANS data on Nb/FePd thin films with
perpendicular magnetic anisotropy with results from
CDXRMS,and evaluate our conclusions together with
information gained by Density Functional Theory(DFT) [1]. In
study (ii), we present the dependence of magnetic chiral
phases occurring in the magnetoelectricsingle crystal
Ba2−xSrxMg2Fe12O22 [2] as function of temperature and
magnetic field.[1] P. C. Carvalho et al., Nano Lett. 23,
