“…This is in comparison to about 20 pT/Hz 1/2 at 1 Hz for ME sensors without annealed Metglas, as previously reported. 18 In conclusion, giant values of a ME have been found in self-biased annealed Metglas/PZT/Metglas laminates under zero magnetic field. A magnetic interaction can shift the M-H hysteresis loops in annealed Metglas/Metglas bilayers.…”

“…These can be employed to reduce the equivalent magnetic noise via an increase in the signal gain without the introduction of additional noise sources [33]. Stressed magnetostrictive materials have a higher piezomagnetic coefficient, and in turn stress can be used to reduce the equivalent magnetic noise via enhancing the ME charge coefficient [34,35]. Single-crystal piezoelectrics, for example lead magnesium niobate-lead titanate (PMN-PT) single crystals, exhibit ultrahigh piezoelectric coefficients of approximately 2000 pC N −1 and low tan δ value of approximately 0.005.…”

Since the turn of the millennium, multi-phase magnetoelectric (ME) composites have been subject to attention and development, and giant ME effects have been found in laminate composites of piezoelectric and magnetostrictive layers. From an application perspective, the practical usefulness of a magnetic sensor is determined not only by the output signal of the sensor in response to an incident magnetic field, but also by the equivalent magnetic noise generated in the absence of such an incident field. Here, a short review of developments in equivalent magnetic noise reduction for ME sensors is presented. This review focuses on internal noise, the analysis of the noise contributions and a summary of noise reduction strategies. Furthermore, external vibration noise is also discussed. The review concludes with an outlook on future possibilities and scientific challenges in the field of ME magnetic sensors.

“…Sometimes, the experimenter needs to calculate the optimal conditions to obtain the desired effect in order to perform experiments. In [ 40 ], two methods to effectively self-stress induce on Metglas/Pb(Zr,Ti)O 3 /Metglas ME composite are considered: applying a DC electric field to the core piezoelectric composites and other applying a DC magnetic field to the layers of Metglas. Multi-push–pull L-L mode Metglas/PZT/Metglas composites were fabricated during the research.…”

One of the new materials that have recently attracted wide attention of researchers are magnetoelectric (ME) composites. Great interest in these materials is due to their properties associated with the transformation of electric polarization/magnetization under the influence of external magnetic/electric fields and the possibility of their use to create new devices. In the proposed review, ME magnetic field sensors based on the widely used structures Terfenol—PZT/PMN-PT, Metglas—PZT/PMN-PT, and Metglas—Lithium niobate, among others, are considered as the first applications of the ME effect in technology. Estimates of the parameters of ME sensors are given, and comparative characteristics of magnetic field sensors are presented. Taking into account the high sensitivity of ME magnetic field sensors, comparable to superconducting quantum interference devices (SQUIDs), we discuss the areas of their application.
