Magnetoelectric properties of bulk 0-3 Fe/BaTiO₃-composites.

ABSTRACT: Magnetoelectric 0-3 Fe _x /(BaTiO₃)_1-x composites (x = 0.1-0.8) were synthesized by reduction of Fe₂O₃/BaTiO₃ pellets in forming gas. In a subsequent sintering step, dense composite ceramics were formed. Depending on the oxygen getter used in the sintering step (carbon or zirconium carbide) a partly iron-doped or undoped ferroelectric barium titanate matrix is obtained, which encloses micrometer-sized ferromagnetic Fe particles. The experimentally determined iron contents derived from Rietveld refinements and magnetic measurements are in good agreement with the nominal ones in the undoped composites. Field dependent magnetoelectric measurements revealed only small differences between the composites with d
