Multiferroics are defined as materials that simultaneously exhibit ferromagnetism and ferroelectricity. Such properties make those materials promising building blocks of novel multifunctional materials for a variety of applications. However, it still remains a great challenge to enhance the ferromagnetism and ferroelectricity of multiferroics.
