A coupled nonlinear circuit for E-field and B-field detection

Multiferroic materials represent a very attractive class of materials due to the coupling between their electric and magnetic orders. A recent paper has demonstrated that a thin film of BDFO shows a good magnetoelectric coupling. Based on such a peculiarity, multiferroic composites can be successfully used to realize sensors of both electric and magnetic fields. This work reports two different ways to realize an E-field and B-field sensor with a thin layer of BDFO. The first approach shows as a single multiferroic device can be used as sensor, while the second approach exploits a coupled system made by three multiferroic devices. The multiferroic device models are presented together with the electronic circuits used in the simulations.
