Claim:
1. A piezoelectric device, comprising: (a) a thin piezoelectric substrate film; (b) a pattern of a plurality of paired top electrodes on a top surface of said piezoelectric substrate film, each top electrode pair oriented linearly; (c) a continuously planar bottom electrode mounted to the bottom of said piezoelectric substrate film; and (d) one or more magnetostrictive islands on said top surface of the piezoelectric substrate film located between the top electrodes of at least one pair of top electrodes; (e) wherein each of said top electrodes of the pattern of top electrodes has at least one dimension that is approximately equal to a thickness of said thin piezoelectric substrate film; (f) wherein the piezoelectric substrate film immediately under the top electrodes will elongate out-of-plane and contract in-plane when a potential is applied thereto; and (g) wherein magnetization of said magnetostrictive islands can be controlled by a voltage applied to said pairs of top electrodes.
