      abstract     = {Zero field cooled (ZFC)/Field Cooled (FC) magnetization
                      curves of a bulk MnO single crystal show a peculiar peak at
                      low temperatures (~ 40 K) similar to the low temperature
                      peak observed in MnO nanoparticles. In order to investigate
                      the origin of this peak, the spin structure of a MnO single
                      crystal has been studied and compared with a single phase
                      powder sample using magnetometry and polarized neutron
                      scattering. Both magnetometry and polarized neutron
                      diffraction results confirm the antiferromagnetic (AF) phase
                      transition at the Néel temperature TN of 118 K, in both
                      powder and single crystal form. However, the low temperature
                      peak in the ZFC/FC magnetization curves is not observed in
                      single phase MnO powder. To better understand the observed
                      behavior, ac susceptibility measurements have been employed.
                      We conclude that the clear peak in the magnetic signal from
                      the single crystal originates from a small amount of
                      ferrimagnetic (FiM) Mn2O3 or Mn3O4 impurities, which is
                      grown at the interfaces between MnO crystal twins.},
