The magnetoelectric (ME) effect, with cross-correlation coupling between magnetic and electric degrees of freedom, is associated with two promising application scenarios: magnetic field sensors and electric-write magnetic-read memory devices. In this review, we highlight recent progress in ME laminates for sensor applications, in particular with regards to the most difficult technical obstacle to their practical use (i.e. reduction of equivalent magnetic noise), while presenting an evolution of ME materials. The challenges and perspectives for the technical obstacles that would enable ME composites for sensor applications are emphasized.
