Influence of Cr-doping on structural, morphological, optical, dielectric and magnetic properties of KNbO 3 ceramics

In this work, we report on the structural, morphological, optical, dielectric and magnetic properties of undoped and Cr doped KNbO3 (KNb1-xCrxO3; x = 0.0, 0.01, 0.03 and 0.05 mol.%) synthesized at 900 °C by solid state reaction method. X-ray diffraction analysis showed the formation of single phase KNbO3 with the orthorhombic structure. Further, the Rietveld refinement analysis revealed that no impurity or secondary phase formation related to...
