In this work, the magnetoelectric response in a series of Dy1-xHoxMnO3 crystals with substitution x from 0 to 0.4 was investigated. The measurement results showed that, as x increases, a decrease in both the polarization Pa and the magnitude of the susceptibility of the inverse magnetoelectric effect αba is observed. In addition, the field Hb increases, at which the Pc→Pa transition is observed, and the temperature range of the existence of the magnetoelectric response decreases. Thus, an increase in the substitution x suppresses the magnetoelectric effect in this series of compounds. The measurement results also indirectly indicate the prolongation of the Pa state and, consequently, of the magnetic state with a cycloid lying in the ab-plane by an external electric field Ea.The reported study was funded by Russian Foundation for Basic Research, Government of Krasnoyarsk Territory, Krasnoyarsk Regional Fund of Science to the research project No.20-42-243008.
