Ferroelectric phase transition in multiferroic Ge(1−x)Mn(x)Te driven by local lattice distortions

The evolution of local ferroelectric lattice distortions in multiferroic Ge(1−x)Mn(x)Te is studied by x-ray diffraction, x-ray absorption spectroscopy and density functional theory. We show that the anion/cation displacements smoothly decrease with increasing Mn content, thereby reducing the ferroel...
