Magnetically induced electric polarization reversal in multiferroic TbMn${}_2$O${}_5$: Terbium spin reorientation studied by resonant x-ray diffraction

R. D. Johnson, C. Mazzoli, S. R. Bland +2

In multiferroic TbMn${}_2$O${}_5$, the behavior of the terbium ions forms a crucial part of the magneto-electric coupling. The result is a magnetically induced reversal of the electric…
