Magnetoelectric sensors: A review

Multiferroic materials possess at least two fundamental properties of ferroelectricity, ferromagnetism, and ferroelasticity. This advanced coupling effect between different properties endows multiferroic materials with new characteristics. As a result, these materials have high potential for applications in various fields. One characteristic that the magnetoelectric (ME) coupling effect can achieve is electric-field-controlled magnetization or magnetic-field-controlled polarization. This effect opens a new direction for the development of low-power and small-sized electronic devices. This review first provides a brief introduction of the development history and recent studies of ME materials. We then introduce the latest research progress on ME sensors and summarize their engineering applications in magnetic detection. Finally, we conclude by addressing potential future work on ME effect enhancement and potential engineering applications.
