Abstract

Abstract: 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 53 nm to 106 nm. The VSM was employed for magnetic studies between − 10, 000 Oe and 10, 000 Oe range. Considerable high value of 'Hc' coercivity (1581 Oe) and an enhanced value of 'Ms' saturation magnetization (51 emu/g) have been obtained as result of substitution. The value of Hc is high enough value but in soft ferrite range. Hence synthesized LiCo0.5 Prx Fe2−x O4 ferrites are suitable for high density storage devices application.
