abstract = {The implementation of anisotropy to functional materials is
a key step towards future smart materials. In this work, we
evaluate the influence of preorientation and sample
architecture on the strain-induced anisotropy in hybrid
elastomers containing covalently attached elongated magnetic
filler particles. Accordingly, silica coated spindle-type
hematite particles are incorporated to
poly(dimethylsiloxane)-based elastomers, and two types of
composite architectures are compared: On the one hand a
conventional architecture of filled, covalently crosslinked
elastomers, and on the other hybrid elastomers that are
crosslinked exclusively by covalent attachment of the
polymer chains to the particle surface. By the application
of external strain and with magnetic fields, the
orientational order of the elongated particles can be
manipulated, and we investigate the interplay between
strain, magnetic order, and orientational order of the
particles by combining 2D small angle X-ray scattering
experiments under strain and fields with Mössbauer
spectroscopy under similar conditions, and supplementary
angular-dependent magnetization experiments. The converging
information is used to quantify the order in these
interesting materials, while establishing a direct link
between the magnetic properties and the spatial orientation
of the embedded magnetic nanoparticles.},
