Introduction Composite and single-phase multiferroic materials, such as Ni1−xZnxFe2O4/lead zirconate titanate multilayers and singlephase BiFeO3,1 have been a major research focus of late due to their versatile functionalities for a wide range of applications that take advantage of its strong magnetoelectric (ME) coupling.2–8 Multiferroic materials are defined as having two or more of the ferroic properties such as ferroelectricity, ferromagnetism, and ferroelasticity, where “singlephase” indicates that a single material has two or more of the ferroic properties. Currently, multiferroic composites lead the field due to their ME coupling coefficients being several orders of magnitude higher than those of single-phase multiferroics. The strong ME coupling effect in multiferroic materials has demonstrated good energy conversion between electric and magnetic fields, allowing for practical multiferroic
devices such as sensors and tunable radio-frequency (RF)/ microwave devices. Multiferroic devices can be categorized based on the control mechanism, as shown in Table I. There are two types of ME coupling effects used for practical devices— direct and converse ME coupling. Direct ME coupling (magnetic field control of electrical polarization) has been used in magnetometers and energy harvesters.9,10 Converse ME coupling (with electric-field control of magnetization switching can be used in spintronics, ME random access memory, and other applications.11–13 Converse ME coupling (with electric-field control of magnetic permeability and spin waves has been used in voltage tunable inductors, tunable bandpass filters, and tunable phase shifters. Multiferroic materials with high permeability and high permittivity provide great opportunities for compact RF/microwave
