Multiferroic properties of microwave sintered BaTiO₃–SrFe₁₂O₁₉ composites

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
