Interests: advanced processing and properties of knowledge-based materials: multiferroics, magnetoelectrics, ferroelectrics, piezoelectrics; single-phase perovskite oxides, new solid solutions, and morphotropic phase boundary (MPB); composites including all-oxide materials, metal alloy-oxide, and polymer-oxides; material nanostructuring and size effects, mechanosynthesis, and spark plasma sintering; sensors, actuators, and energy harvesting
Magnetoelectrics are key enabling materials for a range of proposed related technologies that exploit their ability to develop an electric polarization in response to a magnetic field, and conversely of a magnetization in response to an electric one. Examples are electrically-tunable magnetic devices for microwave communications, high-sensitivity magnetic-field sensors with room-temperature operation, and energy harvesters, to name a few. The most promising materials and those closest to enabling the technologies are two-phase materials combining ferroelectrics and ferromagnets. The largest effective room-temperature magnetoelectric coefficients have been obtained for composites of elastically-coupled high-sensitivity piezoelectric and magnetostrictive components. Different piezoresponsive phases and connectivity schemes are under consideration, but mostly ferroelectric oxides and polymers have been used as piezoelectrics, while magnetic metal alloys and oxides are the choice for magnetostrictive components. All 0–3, 1–3, and 2–2 composite configurations are being extensively explored for different applications, and good quality particulate, fiber-type, and laminate composites have been reported. This Special Issue aims at putting together recent advancements in processing, understanding, applications, and novel materials, and finally aims to outline some future technological and scientific challenges in the field of magnetoelectric composites. Contributions on all types of composites, both bulk and film, either experimental or theoretical studies as well as potential technical implementations are welcomed.

Title: Magnetoelectric MEMS Double-Clamped Resonators for Magnetic Field Sensors
Author: Peter Finkel (@nrl.navy.mil)
Abstract: Magnetoelectric (ME) resonators are of significant interest for next generation magnetic field sensors, as the direct coupling of magnetostrictive and piezoelectric phases enables high magnetic field sensitivity with exceptionally low operational power requirements. In this work, we present silicon based ME thin film resonators with clamped-clamped boundary conditions, that are fully suspended to achieve a string mode resonance. An applied magnetic field results in the development of a magnetoelastic stress that shifts the resonance frequency, which can be detected using the piezoelectric layer. In this work we will discuss possible ways to improve limit of detection of this type of sensors.
