    • Bias-field effect on the temperature anomalies of dielectric permittivity in PbMg1/3Nb2/3O3-PbTiO3 single crystals 

      Raevski, I. P.; Prosandeev, S. A.; Emelyanov, A. S.; Raevskaya, S. I.; Colla, Eugene V.; Viehland, Dwight D.; Kleemann, W.; Vakhrushev, S. B.; Dellis, J. L.; El Marssi, M.; Jastrabik, L. (American Physical Society, 2005-11-16)
      In contrast to ordinary ferroelectrics where the temperature T-m of the permittivity maximum monotonically increases with bias field E in (1-x)PbMg1/3Nb2/3O3-(x)PbTiO3 (0 <= x <= 0.35) single crystals, T-m was found to ...
    • Soft phonon columns on the edge of the Brillouin zone in the relaxor PbMg1/3Nb2/3O3 

      Swainson, I. P.; Stock, Chris; Gehring, Peter M.; Xu, Guangyong; Hirota, K.; Qiu, Y.; Luo, Hongjie; Zhao, X.; Li, Jiefang; Viehland, Dwight D. (American Physical Society, 2009-06-10)
      We report lattice-dynamical measurements, made using neutron inelastic-scattering methods, of the relaxor perovskite PbMg1/3Nb2/3O3 (PMN) at momentum transfers near the edge of the Brillouin zone. Unusual "columns" of ...
