Abstract
Complex magnetic, resistive, and dielectric studies of Pr1–xCaxMnO3 (х = 0.15–0.30) manganites reveal multiferroic properties at T≫TC in these solid solutions. States with local magnetization in the form of ferromagnetic clusters (nucleation temperature T* ≈ 700 K) and high dielectric constants coexist in the temperature window TC ≤ T ≤ T*. There is a correlation between the temperature dependences of specific resistance and specific magnetization.
