Abstract

Recently we have reported the observation of colossal magnetostriction effect in HoMn2O5 single crystals. Besides we have made the supposition for possible correlation between the peculiarities, observed in the field depended polarization measurements, and the colossal magnetostriction effect at a 4.2 K temperature. In this article we present our results received by polarization and magnetostriction measurements on HoMn2O5 and TbMn2O5 single crystals and the strong correlation between magnetostriction and polarization phase transition for these two compounds. The origin of this correlation is discussed.
