Predicting Performance of Particulate Magnetoelectric Composites
A mathematical formulation to predict the magnetoelectric properties of particulate composites is developed. Conductivity of the piezoelectric phase is included. The effect of constituent properties and volume fraction on the voltage, charge, and power conversion of the composite can be calculated for any device configuration, including a thin-film deposited on a rigid substrate. Diverse choices can be made for the directions of electrical and magnetic poling, as well as for the location for the electrical interconnects and the direction of the applied magnetic field. The effects of demagnetization are taken into account and thus the actual geometric dimensions of the device are included in the calculations. A few results are included in this paper and more will be discussed during the oral presentation.
