crystal structurephase transitionsdielectric and nonlinear optical properties—Perfect single crystals of BiFeO 3 have been grown by the solution-melt method. Chemical analysis has confirmed their cationic and anionic stoichiometry. Precision X-ray diffraction analysis has provided more accurate structural ...
BiFeO3, the paradigm of single-phase multiferroic materials, has potential applications in information storage, sensors and actuators. This perovskite has a rhombohedral R3c crystallographic structure and shows a spin-modulated cycloidal magnetic structure with a modulation period of 62 nm. It reveals ...
Crystal structure of the Bi1-xBaxFe1-xTixO3 ceramics across the phase boundary region between the polar rhombohedral and pseudo-cubic phases has been investigated by means of X-ray and neutron diffraction, scanning electron microscopy and differential scanning calorimetry techniques. The structural ...

reported a structural transformation from rhombohedral structure for BiFeO3 to triclinic structure for Bi1−xNdxFeO3 (x = 0.05–0.15) and the magnetoelectric coupling was clear in Bi1−xNdxFeO3 (x = 0.15–0.175) near the Néel temperature of ∼653 K whereas, for further Nd doped ...
BiFeO3, the crystal structure of zone I matches none of BiFeO3phases reported experimentally or predicted theoretically. Detailed electron diffraction analysis combined with first-principles calculation allows us to determine that zone I displays an orthorhombic-like monoclinic structure with space group of...
