- The neutron powder diffraction (NPD) measurements of the nano-size $DyMnO_3$ manganite have been performed. The obtained results indicate that this compound crystallizes in the orthorhombic crystal structure described by the space group Pnma. The Mn and Dy moments order antiferromagnetically at different temperatures and form modulated magnetic structure described by the propagation vector k=($k_x$, 0, 0) with the different values of $k_x$ component for the Mn and Dy sublattices. The values of $k_x$ component for Mn sublattice increase with decreasing of the temperature and are smaller that in bulk compound. The wide Bragg peaks related to the Dy sublattice suggest that the magnetic order in this sublattice has the cluster-like character.
