We report on the magnetostriction of hexagonal HoMnO{sub 3} and YMnO{sub 3} single crystals in a wide range of applied magnetic fields (up to H = 14 T) at all possible combinations of the mutual orientations of magnetic field H and magnetostriction ΔL/L. The measured ΔL/L(H, T) data agree well with the magnetic phase diagram of the HoMnO{sub 3} single crystal reported previously by other authors. It is shown that the nonmonotonic behavior of magnetostriction of the HoMnO{sub 3} crystal is caused by the Ho{sup 3+} ion; the magnetic moment of the Mn{sup 3+} ion parallel to the hexagonal crystal axis. The anomalies established from the magnetostriction measurements of HoMnO{sub 3} are consistent with the phase diagram of these compounds. For the isostructural YMnO{sub 3} single crystal with a nonmagnetic rare-earth ion, the ΔL/L(H, T) dependences are described well by a conventional quadratic law in a wide temperature range (4–100 K). In addition, the magnetostriction effect is qualitatively estimated with regard to the effect of the crystal electric field on the holmium ion.
