Аннотация
Crystal and magnetic structures of Dy1 – xHoxMnO3 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. Description was made using the Pbnm group down to very low temperatures for both compounds. Within accuracy of the measurements, magnetic ordering does not change the crystal structure. 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.
