The phase and polycrystalline (grain) structures as well dielectric and thermal properties of Bi1-xTbxFeO3 (where x = 0.05–0.20, Δх = 0.05) magnetoelectric solid solutions were investigated. The regularities of the objects’ phase and grain structures, electrical and dielectric properties formation at room temperature were established. There are two temperature regions (500–600 K and 640–700 K), in which investigated solid solutions ε/ε0, l, χ, Cp, and α temperature dependencies experience anomalies of different types. Based on these results, it was found that TN of Bi1-xTbxFeO3 compounds does not show significant shift when changing x. The conclusion about an opportunity of received results use when creating a new generation of multifunctional materials was made
