Ferromagnetism in metal oxide systems: interfaces, dopants, and defects
TLDR
A review of the developments in this field by late 2011 and 2012 can be found in this paper, where a number of techniques are applied to bring out materials issues that are critical to the precise understanding of the origin of magnetism in certain cases.Abstract:
Ferromagnetism in metal oxide systems has always attracted scientific attention in view of the intriguing and interesting interplay of spin, charge, orbital and lattice degrees of freedom that such systems display. This trend appears to be continuing with enhanced focus on interface systems, multiferroics, diluted magnetic semiconducting oxides (DMSOs) and nanomaterial magnetism. Newer techniques are being applied to bring out materials issues that are critical to the precise understanding of the origin of magnetism in certain cases. Interest is also beginning to grow in exploring application potential of some such systems. In this article we review the developments in this field by late 2011 and 2012.read more

TL;DR: This article can reversibly switch between two distinct exchange-bias states by switching the ferroelectric polarization of BiFeO(3), an important step towards controlling magnetization with electric fields, which may enable a new class of electrically controllable spintronic devices and provide a new basis for producing electrically controlled spin-polarized currents.

Electric-field-induced spin flop in BiFeO3 single crystals at room temperature.
TL;DR: It is argued here that the coupling between the two orders may be stronger in the bulk than in thin films where the cycloid is absent, and that the antiferromagnetic and ferroelectric order parameters are intimately coupled.
