abstract = {HEiDi and POLI are the only single-crystal neutron
diffractometers in Germany and two of the very few in the
world which are located at a hot neutron source to enlarge
the flux of neutrons with short wavelengths. It allows to
minimize the absorption problems associated with certain
elements and to explore extremely large portions of
reciprocal space. HEiDi is a typical 4-circle diffractometer
with Eulerian cradle for detailed studies on crystal and
magnetic structures in the temperature range 2.5–1300 K.
POLI is an independent diffractometer, which extends the
possibilities of HEiDi to the milli-Kelvin range and
external magnetic fields as well as offers in addition
different types of polarized neutron techniques:
Flipping-ratio measurements in applied magnetic field for
ferromagnetic and paramagnetic materials and spherical
neutron polarimetry in zero field for more complex magnetic
structures. Due to their possibilities, both instruments
contribute to many topics, e.g. in the energy and
information sector. Here, on examples of multiferroic and
superconducting materials, we give an overview of the
instruments possibilities in studying of crystal and
magnetic structures and phase transitions of solids in
general, and their crystallographic and magnetic domains
(microstructures) in particular.},
