A novel “one-pot” synthetic method has been reported for the preparation of (NiFe2O4)x–(BaFe12O19)1−x composites. The synthesized composites were characterized using thermogravimetric analysis, differential scanning calorimetric analysis, X-ray diffraction, dynamic light scattering technique, scanning electron microscopy, and vibrating sample magnetometer. The (NiFe2O4)x–(BaFe12O19)1−x composites prepared by this method showed crystallographically two phase behavior, but magnetically a good single phase exchange spring-coupled behavior with high saturation magnetization as well as high coercivity.
