摘要：We report on structural, magnetic, ferroelectric, and thermodynamic properties of polycrystalline orthorhombic manganites Dy_1−xHo_xMnO₃ for Ho substitution levels 0 ≤ x ≤ 1. This system offers a possibility to systemically modulate the multiferroicity of R MnO₃ via tuning the A -site ionic radii as well as the A -site magnetism. The successive transition of the multiferroic ground state is traced from the bc -cycloidal (DyMnO₃) to the E -type antiferromagnetic phase (HoMnO₃). In the middle substitution range 0.4 x
