Magnetic and electric properties of the lead free ceramic composite based on the BFN and ferrite powders

Ferroelectromagnetic BaFe0.5Nb0.5O3 (BFN) ceramics and ferroelectromagnetic composites based on BFN powder and ferrite powder have been obtained in the presented work. The percentage of components in a two-phase composite was: biferroic powder BFN in the amount of 90%, and nickel–zinc ferrite Ni1 − xZnxFe2O4 for x = 0.36 in the amount of 10%. The synthesis of the components of the BFN–ferrite composite was performed using the calcination method. Final densification of the synthesized powder was done using free sintering. e obtained two-phase ceramic BFN–ferrite composite, the XRD, microstructure, EDS, dielectric, impedances, magnetic, Mössbauer and electrical hysteresis loop investigations were performed. The obtained results show correlations between the magnetic subsystem and the electrical subsystem of the ferroelectromagnetic composite. Such properties of the obtained composite give a possibility to use them in memory applications of a new type.
