TL;DR: A one-to-one mapping of the ferroelectric and ferromagnetic domains is discovered, mediated by the colinear coupling between the magnetization in the ferromagnet and the projection of the antiferromagnetic order in the multiferroic.

TL;DR: The observation of an electronic conductor-insulator transition by control of band-filling in the model antiferromagnetic ferroelectric BiFeO3 through Ca doping opens the door to merging magnetoelectrics and Magnetoelectronics at room temperature by combining electronic conduction with electric and magnetic degrees of freedom already present in the multiferroic Bi FeO3.

TL;DR: In this paper, the basics of multiferroics including the important order parameters and magnetoelectric coupling in materials are discussed, and the growth of single phase, horizontal multilayer, and vertical heterostructure multiferraics are discussed.

TL;DR: It is shown that the magnitude of the exchange bias interaction scales with the length of 109 degrees ferroelectric domain walls in the BiFeO 3 thin films which have been probed via piezoresponse force microscopy and X-ray magnetic circular dichroism.

TL;DR: In this paper, the authors describe the evolution of their understanding of the connection between structure, properties, and new functionalities (including electrical control of magnetism) using BiFeO 3 as a model system.
