In this work, the magnetoelectric response in a series of Dy_1-xHo_xMnO₃ 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 P_a and the magnitude of the susceptibility of the inverse magnetoelectric effect α_ba is observed. In addition, the field H_b increases, at which the P_c-> P_a 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 P_a state and, consequently, of the magnetic state with a cycloid lying in the ab-plane by an external electric field E_a. 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. Keywords: multiferroics, magnetoelectric effect, phase transition, ferroelectricity.
