Local structural distortion induced by antiferromagnetic ordering in Bi $_{2}$ Fe $_{4}$ O $_{9}$ studied using neutron total scattering analysis

I. -K. Jeong, N. Hur

To unravel the origin of the dielectric anomaly at the antiferromagnetic ordering of magnetoelectric Bi $_{2}$ Fe $_{4}$ O $_{9}$ we performed neutron powder diffraction measurements across t…

Structural evolution of bismuth sodium titanate induced by A-site non-stoichiometry: Neutron powder diffraction studies

I. -K. Jeong, Y. S. Sung, T. K. Song +2

We performed neutron powder diffraction measurements on (Bi $_{0.5}$ Na $_{0.5 + x}$ )TiO $_{3}$ and (Bi $_{0.5 + y}$ Na $_{0.5}$ )TiO $_{3}$ to study structural evolution induced by the non-stoichi…

Determination of the Local Symmetry and the Multiferroic-ferromagnetic Crossover in Ni3-xCoxV2O8 by using Raman Scattering Spectroscopy

Yu-Seong Seo, Sun-Hwa Kim, Jai Seok Ahn +1

Comprehensive vibrational studies on the multiferroic-to-normal-ferromagnetic crossover in isostructural Ni3-xCoxV2O8 (NCVO, x = 0 - 3.0) are performed using Raman scattering spect…

Soft Modes and Local Structural Transitions in Pb-free Ba(Ti0.8Zr0.2)O3-x(Ba0.7Ca0.3)TiO3 (x = 0.5): Pressure- and Temperature-dependent Raman Studies

Yu-Seong Seo, Jai Seok Ahn, Il-Kyoung Jeong

We report our Raman studies of a new lead-free relaxor ferroelectrics, Ba0.85Ca0.15Ti0.9Zr0.1O3 (BCTZO). The Raman modes of BCTZO are compared with those of BaTi0.8Zr0.2O3 (BTZO),…

Giant Magnetoelectric Effect in a Multiferroic Material with a High Ferroelectric Transition Temperature

N. Hur, I. K. Jeong, M. F. Hundley +2

We present a unique example of giant magnetoelectric effect in a conventional multiferroic HoMnO3, where polarization is very large (~56 mC/m2) and the ferroelectric transition tem…

Limitations on the extent of off-center displacements in TbMnO3 from EXAFS measurements

F. Bridges, C. Downs, T. O'Brien +2

We present EXAFS data at the Mn K and Tb L3 edges that provide upper limits on the possible displacements of any atoms in TbMnO3. The displacements must be less than 0.005-0.01A fo…
