Abstract

|
|
| The structures and the dynamic characteristics of the lattices of two compositions of solid solutions of multiferroic BiFeO3 with ferroelectric KNbO3 and antiferroelctric NaNbO3, namely, (1 - x)BiFeO-xKNbO(3) and (1 - x)BiFeO3-xNaNbO(3), have been studied using X-ray powder diffraction and Raman spectroscopy. For these systems with x = 0.3, 0.5, and 0.7, the symmetry and unit cell parameters at room temperature have been determined. An analysis of the vibrational spectra has revealed sequences of rotational distortions with variations in the concentrations of components. |
