Abstract: Crystal and magnetic structures of Dy$_{1–x}$Ho$_{x}$MnO$_{3}$ multiferroic single crystals (x = 0, 0.2) were investigated by the neutron diffraction methods. It is shown that the substitution of Dy by Ho at the level of 20% does not change the crystal symmetry of the compound, which is described by the Pbnm space group for both compounds down to lowest temperatures and magnetic ordering does not change the crystal structure within accuracy of the measurements. Substitution of Dy by Ho suppresses spontaneous ordering of a rare-earth subsystem with a propagation vector (0 0.5 0). This leads to a situation when two magnetic subsystems, manganese and rare-earth ones, have a coherent incommensurate space propagation.
