Evidence for room-temperature multiferroicity in a compound with a giant Axial Ratio.
Physical review letters, 2009Co-Authors: Hélène Béa, Bertrand Dupé, Stéphane Fusil, Richard Mattana, Eric Jacquet, Bénédicte Warot-fonrose, Fabrice Wilhelm, Andrei Rogalev, Sylvain Petit, Vincent CrosAbstract:In the search for multiferroic materials magnetic compounds with a strongly elongated unit-cell (large Axial Ratio $c/a$) have been scrutinized intensely. However, none was hitherto proven to have a switchable polarization, an essential feature of ferroelectrics. Here, we provide evidence for the epitAxial stabilization of a monoclinic phase of ${\mathrm{BiFeO}}_{3}$ with a giant Axial Ratio ($c/a=1.23$) that is both ferroelectric and magnetic at room temperature. Surprisingly, and in contrast with previous theoretical predictions, the polarization does not increase dramatically with $c/a$. We discuss our results in terms of the competition between polar and antiferrodistortive instabilities and give perspectives for engineering multiferroic phases.
