Phosphate bonded CoFe<sub>2</sub>O<sub>4</sub>–BaTiO<sub>3</sub> layered structures: Dielectric relaxations and magnetoelectric coupling
Abstract
<jats:p>Multilayered phosphate bonded CoFe<jats:sub>2</jats:sub>O<jats:sub>4</jats:sub>–BaTiO<jats:sub>3</jats:sub>–CoFe<jats:sub>2</jats:sub>O<jats:sub>4</jats:sub> (CBC) and BaTiO<jats:sub>3</jats:sub>–CoFe<jats:sub>2</jats:sub>O<jats:sub>4</jats:sub>–BaTiO<jats:sub>3</jats:sub> (BCB) multiferroic structures were formed by means of uniaxial pressing. The dielectric properties were studied in 20 Hz – 1 GHz frequency and 120–500 K temperature ranges. The complex dielectric permittivity is 15–0.17i for CBC and 22–0.04i for BCB, it is temperature- and frequency-independent below 250 K. At higher temperatures, strong dispersion appeared governed by the Maxwell–Wagner relaxation. Such behaviour is determined by the 2–2 connectivity of the sample. The highest direct magnetoelectric coupling coefficient was found for the BaTiO<jats:sub>3</jats:sub>–CoFe<jats:sub>2</jats:sub>O<jats:sub>4</jats:sub>–BaTiO<jats:sub>3</jats:sub> structure of 0.2 mVOe<jats:sup>–1</jats:sup>cm<jats:sup>–1</jats:sup>.</jats:p>
