Abstract

This paper reports the magnetoelectric properties of CoFe₂O₄-BaTiO₃ core-shell structure composites. Crystalline structures of the composites were investigated by X-ray diffractometer (XRD). Magnetic properties were studied using a pulse field magnetometer. Magnetostriction was measured using strain gauge method. AC susceptibility and ME coefficient were investigated using lock-in technique in which AC fields with frequencies from 1 Hz to 4 kHz and amplitudes from 0.1 Oe to 20 Oe superimposed onto a DC magnetic field up to 6500 Oe were employed. All measurements were carried out at room temperature and ambient pressure.
