Multiferroic properties of microwave sintered BaTiO < inf > 3 < /inf > -SrFe < inf > 12 < /inf > O < inf > 19 < /inf > composites

Abstract

The composites of xSrFe12O19-(1-x) BaTiO3 where x=0, 0.1, 0.3, 0.5, 0.7, 0.9 and 1were prepared by Sol-gel method and consequently densified at 1100 °C/90 min using microwave sintering method. The phase formation and diphase microstructure of the composite samples was examined by X-ray diffraction and field emission electron microscope (FESEM), respectively. The effects of constituent phase variation on the ferroelectric, dielectric and magnetic properties were examined. It was observed that with a decrease of x, the Curie temperature shifted towards low temperature side. © 2014 Elsevier B.V.
