“…In addition to the self-biased behavior in graded composite, it was observed that FeCo/Ni/ PZT/Ni/FeCo and Ni/PZT/Ni yielded the best quasi-static and resonant responses, respectively. In a later development, the effect of Co content in NiCo magnetostrictive layer was studied, wherein the composition of FeCo was changed by varying the bath composition [142]. It was inferred that maximum ME response improves significantly from 100 to 330 mV cm −1 Oe when Co content in NiCo decreases from 55% to 17%.…”

Layered or 2-2 conﬁguration magnetoelectric (ME) composites have gained signiﬁcant interest in the last few decades owing to their ease of fabrication and relatively high ME output realizable at room temperature. Conventionally, layered ME composites are fabricated by bonding the constituent magnetostrictive and piezoelectric layers via an epoxy or adhesive. Thus, the epoxied interface acts as the medium of strain transfer between the constituent layers resulting in the ME effect. However, the presence of epoxy makes the composite prone to limitations such as reduced device life due to aging epoxy, reduced strain transfer efﬁcacy due to low stiffness of epoxy, and degradation of composite properties at elevated temperatures due to the low glass transition temperature of epoxy material. Thus, various epoxy-free methods for layered or 2-2 type ME composite fabrication have been developed in the last two decades to circumvent these limitations. These methods include co-ﬁring technique, electroless deposition, electrodeposition, shrink-ﬁt, and press-ﬁt. Each of these methods has tried to mitigate the disadvantages of its predecessors, however posing its own set of limitations. This review article captures the evolutionary journey of the development of each of these aforementioned techniques in a chronological sequence by highlighting the advantages and disadvantages offered by each of them. Subsequently, a brief overview of state of the art has been provided in summary, followed by a discussion on the potential avenues that may be probed further to improve the available epoxy-free fabrication techniques for layered or 2-2 ME composites.

The efficiency of strain-mediated magnetoelectric composites is heavily reliant on the effectiveness of strain transfer between the different constituents. Many analytical and experimental studies have trialed various materials, geometries, and boundary conditions reporting the effect of these attributes on the magnetoelectric response. However, a more sophisticated, but not yet pursued, approach is to investigate the strain distribution in order to discern the factors that are most influential and to provide insight on how these factors should be manipulated to optimize the coupling efficacy. In this study, a mathematical model is developed to observe the radial and tangential strains in a concentric cylinder composite structure consisting of a piezoelectric outer layer bonded with a thin elastic layer to an inner piezomagnetic layer. Results from the study elucidate that the strain distribution behavior was dependent on the mechanical properties of the constituents as well as the bonding condition. Remarkably, analytical results showed that the direct magnetoelectric coefficient can be substantially enhanced, if probing takes place at strategic locations, i.e., leveraging strain localization, on the piezoelectric layer that maximize the difference between the radial displacements giving rise to higher magnetoelectric response.
