Phase transitions in single-crystalline magnetoelectric LiCoPO4
A. Szewczyk, M. U. Gutowska, J. Wieckowski +6
Specific heat, magnetic torque, and magnetization studies of LiCoPO4 olivine are presented. They show that an unique set of physical properties of LiCoPO4 leads to the appearance o…
Relativistic analysis of magnetoelectric crystals: extracting a new 4-dimensional P odd and T odd pseudoscalar from Cr_2 O_3 data
Friedrich W. Hehl, Yuri N. Obukhov, Jean-Pierre Rivera +1
Earlier, the linear magnetoelectric effect of chromium sesquioxide Cr_2 O_3 has been determined experimentally as a function of temperature. One measures the electric field-induced…
Relativistic nature of a magnetoelectric modulus of Cr_2O_3-crystals: a new 4-dimensional pseudoscalar and its measurement
Friedrich W. Hehl, Yuri N. Obukhov, Jean-Pierre Rivera +1
Earlier, the magnetoelectric effect of chromium sesquioxide Cr_2O_3 has been determined experimentally as a function of temperature. One measures the electric field-induced magneti…
The beta Phase of Multiferroic Bismuth Ferrite and its beta-gamma Metal-Insulator Transition
R. Palai, R. S. Katiyar, H. Schmid +5
We show that epitaxial (001) thin films of multiferroic bismuth ferrite BiFeO3 are monoclinic at room temperature instead of tetragonal or Rhombohedral as reported earlier . We rep…
Commensurate-Incommensurate Magnetic Phase Transition in Magnetoelectric Single Crystal LiNiPO
D. Vaknin, J. L. Zarestky, J. -P. Rivera +1
Neutron scattering studies of single-crystal LiNiPO reveal a spontaneous first-order commensurate-incommensurate magnetic phase transition. Short- and long-range incommensurate…
