The magnetoelectric effect in the ring shape magnetostrictive-piezoelectric structures

We have theoretically and experimentally studied the direct magnetoelectric (ME) effect in ring structures made of volume ferrite–piezoelectric composites based on lead zirconate titanate and nickel ferrite. Analytical expressions for the ME voltage coefficient are obtained by jointly solving elastodynamic and electrostatic equations. Results of theoretical calculations and experimental measurements for various geometric parameters of the ring structures are presented.
