Abstract

Iron doped Ba0.6Sr0.4TiO3 (B0.6S0.4Ti1-xFexO3) ceramics have been synthesized using slow injection sol-gel technique and calcined at 1000 o C. The dopant concentration and processing control conditions were varied in order to investigate the structural and magnetic saturation of iron doped barium strontium titanate materials (BSTF). X-ray diffraction analysis revealed that these materials crystallized in perovskite structure. Scanning electron microscopy (SEM) analysis showed that the grains were of irregular grain shapes with the size in the range of 34 - 106 nm. Elemental analysis by energy dispersive spectroscopy (EDS) confirmed that the prepared BSTF materials had the correct stoichiometry. On the other hand, the magnetic saturation (Ms) has been increased by a factor of 3 to 4.35 times when the doping level increased from 0.15 to 0.30.
