Multiferroics : fundamentals and applications

Multiferroics, materials with a coexistence of magnetic and ferroelectric order, provide an efficient route for the control of magnetism by electric fields. The authors cover multiferroic thin-film heterostructures, device architectures and domain/interface effects. They critically discuss achievements as well as limitations and assess opportunities for future applications. - Treats all aspects from theory, characterization to materials synthesis of multiferroics. - Describes thin-film heterostructures and device architectures. - Discusses domain and interface effects.
