説明
<jats:p> The magnetoelectric property of composite materials consisting of piezoelectric and piezomagnetic constituents are of interest since the stresses induced in them on application of an external magnetic field are converted into electrical signals. The electrical output is primarily due to electromagnetic coupling between the two participating phases. The present paper deals with the evaluation of the electromechanical coupling in the magnetoelectric composite consisting of 50% lead zirconate titanate (Pb<jats:sub>0.96</jats:sub>Sr<jats:sub>0.04</jats:sub>Ti<jats:sub>0.47</jats:sub>Zr<jats:sub>0.53</jats:sub>O<jats:sub>3</jats:sub>) and 50% CoFe<jats:sub>2</jats:sub>O<jats:sub>4</jats:sub>, the composition having maximum magnetoelectric conversion efficiency. A sum rule is proposed to calculate the electromechanical coupling coefficient and the results are correlated with the experimental data. </jats:p>
