Anisotropy of magnetoelectric properties of ferrite–piezoelectric bulk composites

The anisotropy of magnetoelectric properties of lead zirconate–titanate and nickel ferrite based bulk composites has been experimentally studied. It has been shown that a ratio of longitudinal to transverse magnetoelectric coefficients is affected by the piezoelectric constant of a composite. The mechanism that explains the obtained dependences has been suggested; the mechanism is based on the assumption that the anisotropy of magnetic properties is caused by the deformation occurring at electric polarization of a sample.
