Effect of BiFeO3 on the properties of the ferroelectric system lead free K0.5Na0.5NbO3

In order to obtain a multiferroic material, powders and ceramic pieces, of the lead-free ferroelectric (1-x)-x K0.5Na0.5NbO3 (Bi0.8La0.2)FeO3 (KNN-BLFO) (x = 0.005, 0.010, 0.015, 0.020, 0.025) system were prepared using the combustion reaction method. For all the studied perovskite phase, stoichiometries feature KNN was obtained. Using characterisation techniques, it was determined that the BLFO is incorporated in the crystal structure of KNN without modifying present a phase transition. Moreover, It was also proved that the addition of the BLFO to KNN, alters the particle size of the obtained powders and generates magnetic behavior in this ferroelectric. (Author)
