TL;DR: In this article, the influence of deposition pressure and temperature on the growth of BiFeO3 thin films by pulsed laser deposition onto (001)-oriented SrTiO3 substrates was explored.

TL;DR: Ab initio calculations of realistic interface structures provide insight into the origin of the induced moments and bring support to this new approach for creating room-temperature multiferroics.

TL;DR: The control of magnetism by electric fields is an important goal for the future development of low-power spintronics as discussed by the authors, and various approaches have been proposed on the basis of either single-phase multiferroic materials or hybrid structures in which a ferromagnet is influenced by the electric field applied to an adjacent insulator.

TL;DR: Surprisingly, and in contrast with previous theoretical predictions, the polarization does not increase dramatically with c/a, so there is evidence for the epitaxial stabilization of a monoclinic phase of BiFeO3 with a giant axial ratio that is both ferroelectric and magnetic at room temperature.

TL;DR: It is revealed that strain progressively drives the average spin angle from in-plane to out-of-plane, a property used to tune the exchange bias and giant-magnetoresistive response of spin valves.
