Abstract: |
Substituted strontium ferrite SrFe12−xCrx/2Alx/2O19 (x=0–2.5) nanoparticles were synthesized by a sol- gel method. 57Fe Mössbauer spectroscopy 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.The chemical 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. |
