Magnetoelectric and electric measurements of the (1-x)BiFeO3-(x) Pb(Fe1/2Nb1/2)O-3 solid solutions
In the paper ferro electro magnetic (1-x)BiFeO3-(x)Pb(Fe1/2Nb1/2)O-3 (BF-PFN) solid solutions were obtained (containing the percentage BF/PFN: 60/40 and 70/30). Individual components of the solid solution were prepared by follows methods: synthesizing a powder BF was performed by calcining the simple oxides (Bi2O3, Fe2O3), and synthesizing a powder PFN was carried out by calcining a mixture of complex oxides (FeNbO4, PbO). Compaction of synthesized and mixed BiFeO3, PbFe1/2Nb1/2O3 powders was carried out by free sintering methods. X ray, microstructure, dielectric, magnetic and magnetoelectric studies, DC electrical conductivity and electrical hysteresis loop were carried out. Magnetoelectric effect measurements performed at room temperature showed coupling between electric and magnetic subsystem of the BF-PFN solid solutions. (C) 2017 Elsevier B.V. All rights reserved.
