Electrical field control of magnetism has been attracting a great amount of recent interest due to its potential technological impacts. The coexistence of electrical polarization and magnetization in multiferroic materials provides great opportunities for realizing effective electric field control, or vice versa, through a strain mediated magnetoelectric interaction effect in layered magnetic/ferroelectric multiferroic heterostructures. Strong magnetoelectric coupling has been the enabling factor for different multiferroic devices, which however has been hard to achieve, particularly at RF/microwave frequencies. In this presentation, we will cover the most recent progress on novel layered microwave multiferroic heterostructures and devices. We will demonstrate strong magnetoelectric coupling in novel microwave multiferroic heterostructures.
