One-magnon (electromagnon) light scattering in BiFeO3 single crystals
Manoj K. Singh, Ram S. Katiyar, J. F. Scott
We observed Raman scattering from magnon in frequency range from 10 to 65 cm-1 in BiFeO3 single crystals at cryogenic temperatures; the temperature dependence of the magnon frequen…
The structural and magnetic properties of (In1-xFex)2O3 (0.0 <= x <= 0.25) system : prepared by gel combustion method
O. D. Jayakumar, I. K. Gopalakrishnan, S. K. Kulshreshtha +9
(In1-xFex)2O3 polycrystalline samples with x = (0.0, 0.05, 0.10, 0.15, 0.20 and 0.25) have been synthesized by a gel combustion method. Reitveld refinement analysis of X raydiffrac…
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…
Behavior of Optical Phonons near the Diffuse Phase Transition in Relaxor Ferroelectric PbMg1/3Ta2/3O3
S. G. Lushnikov, S. N. Gvasaliya, R. S. Katiyar
Raman scattering in relaxor ferroelectric PbMg1/3Ta2/3O3 (PMT) was investigated in the single crystalline form in the temperature range of 20 - 295 K. Anomalous temperature depende…
