Abstract

<jats:p> The structure, dielectric characteristics, and magnetoelectric effect of multiferroic 0.5BiFeO3–0.5PbFe0.5Nb0.5O3 ceramics were studied. Ceramics are found to be pure. At room temperature, ceramics has a cubic structure close to а = 3.999(5) Å, which remains in the temperature range of 20–600 оС. It was shown that 0.5BiFeO3–0.5PbFe0.5Nb0.5O3 solid solution at Т &lt; 200 оС 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. </jats:p>
