Abstract: The structure, dielectric characteristics, and magnetoelectric effect of multiferroic 0.5BiFeO$_{3}$–0.5PbFe$_{0.5}$Nb$_{0.5}$O$_{3}$ ceramics were studied. Ceramics are found to be pure. At room temperature, ceramics has a cubic structure close to $a$ = 3.999(5)$\mathring{\mathrm{A}}$, which remains in the temperature range of 20–600$^\circ$С. It was shown that 0.5BiFeO$_{3}$–0.5PbFe$_{0.5}$Nb$_{0.5}$O$_{3}$ solid solution at $T<$ 200$^\circ$С combines both ferroelectric and antiferromagnetic properties. At room temperature in a constant magnetic field of 0.86 T, magnetodielectric coefficient and dielectric loss in the material are – 0.4% and – 0.5%, respectively.

Keywords: multiferroic, dielectric characteristics, ferroelectric-relaxor, magnetodielectric effect.
