Abstract

The nanocomposite (BiFeO3)0.7-(SrFe12O19)0.3 has been prepared by a sol-gel route and characterized by XRD, TEM, TGA/DTA, dc magnetization and 57Fe Mössbauer spectroscopy. The hyperfine parameters obtained from Mössbauer spectroscopy indicate formation of pure hexaferrite phase of SrFe12O19 (SRF) in the nanocomposite (NC). The NC exhibits typical hysteresis loops with significantly altered magnetization parameters (saturation magnetization, coercivity and remnant magnetization) in comparison with that of the pristine SRF and BiFeO3 (BFO) nanoparticles (NPs). The ZFC-FC curves show a divergence in low temperature region which confirms the irreversible character of magnetization.
