SYNTHESIS AND EVALUATION OF STRUCTURAL AND MAGNETC PROPERTES OF CrA SUBSTITUTED STRONTUM FERRTE NANOPARTICLES

Substituted strontium ferrite Srfe12Cr,Al,019 (xF0–2.5) nanoparticles were synthesized by a solgel method. Fe Mössbauerspectroscopy were used to analyze the structure, static and dynamic magnetic properties of the prepared samples. Mössbauer spectra show that Al-Cr ions preferentially occupy the 12k sites.Thechemical composition of products were identified by FTIR.Field emission scanning electron microscopy microgeraphs demonstrated that the particle size of synthesized samples were in the range of 50 to 100 nanometers.
