چکیده انگلیسی
Praseodymium substituted nano crystalline LiCo spinel ferrites with different concentrations were fabricated by micro-emulsion route. TGA, X-ray diffraction and magnetic properties was employed to study the effect of substitution of the Pr on the structure and magnetic parameters. XRD confirmed the formation of the single phase spinel ferrites with minor coexistence of orthophase. The particle size from XRD data was calculated in range from 53Â nm to 106Â nm. The VSM was employed for magnetic studies between â 10,000Â Oe and 10,000Â Oe range. Considerable high value of 'Hc' coercivity (1581Â Oe) and an enhanced value of 'Ms' saturation magnetization (51Â emu/g) have been obtained as result of substitution. The value of Hc is high enough value but in soft ferrite range. Hence synthesized LiCo0.5PrxFe2âxO4 ferrites are suitable for high density storage devices application.
