      abstract     = {A dedicated polarized neutron diffraction (PND) setup,
                      using a symmetric-field high Tc superconducting magnet with
                      a maximal field of 2.2 T in combination with a ³He
                      polarizer and Mezei-type flipper, has been developed at the
                      instrument POLI. Each component is optimized by numerical
                      simulations and the complete setup is successfully tested
                      and calibrated.This new PND setup was used to collected
                      flipping-ratio (FR) data as function of the applied magnetic
                      field and temperature for different antiferromagnetic
                      compounds. A new advanced approach for the reconstruction of
                      maximum entropy spin density maps from FR measurements is
                      presented. Using this approach, 3D spin density maps can be
                      built for the first time not only for the paramagnetic, but
                      also for the antiferromagnetic phase. These 3D maps reveal
                      new features compared to the results from conventional
                      maximum entropy software and might be used to directly
                      visualize magnetic multipoles.},
