In multiferroic materials, a stable electric polarization can be controlled by applying an external magnetic field and vice versa, as mediated by the magnetoelectric (ME) coupling. Such a unique property makes these systems extremely useful for many technological applications ranging from tunable multifunctional spintronics to magnetoelectric random access memory devices and many kinds of optoelectronic devices.1,2 Physically, as pointed out by Aizu3 and later on by other authors,4,5 the ME coupling between magnetism and ferroelectricity is governed by a simultaneous breaking of inversion and time-reversal symmetries. Since its first prediction,3 the search for multiferroic materials6,7 has become one of the most active research areas in condensed matter and material physics. In particular, the ongoing search for room-temperature multiferroic systems has never been felt more essential.
