Abstract Magnetic properties of the material with more than two crystal phases are found better as compared to that of single crystal phase material. Hence, nanocomposites with different weight percentages of Barium Hexaferrite (BaFe12O19/BHF) in Barium Titanate (BaTiO3/BTO) matrix have been prepared. The X-ray diffraction patterns of BHF, BTO and nanocomposites reveal the absence of other secondary crystal phases. The Raman spectra analysis supports to the XRD patterns analysis. The presence of both BHF and BTO crystal phases in the nanocomposites have been confirmed by the high resolution transmission electron microscopy. Interestingly, the nanocrystalline BTO exhibits weak ferromagnetic behavior. Magnetic interaction between BTO and BHF in the bi-magnetic BTO-BHF composite has been observed.
