|Abstract:||Mn<sup>2+</sup> substituted Zn ferrite nanoparticles have been synthesized using two different wet methods, sol-gel and co-precipitation. The doping effect of Mn<sup>2+</sup> ion concentration on physical properties like structural and magnetic properties is investigated. The crystallite size and lattice parameter increases with increasing Mn<sup>2+</sup> concentration. EPR study reveals that the line width and <i style="mso-bidi-font-style:normal">g</i>-factor increases with increasing Mn<sup>2+</sup> concentration for co-precipitated particles whereas the reverse trend for sol-gel technique is observed. However, in both the processes the saturation magnetization (<i style="mso-bidi-font-style:normal">M</i><sub>s</sub>) and coercivity (<i style="mso-bidi-font-style:normal">H</i><sub>c</sub>) increase with increasing Mn<sup>2+</sup> concentration. In a comparative study, the nanoparticles synthesized by<sub> </sub>sol-gel are more crystalline in nature as compared to co-precipitated particles.|
