| Abstract: | Mn2+
substituted Zn ferrite nanoparticles have been synthesized using two different
wet methods, sol-gel and co-precipitation. The doping effect of Mn2+
ion concentration on physical properties like structural and magnetic properties
is investigated. The crystallite size and lattice parameter increases with
increasing Mn2+ concentration. EPR study reveals that the line width
and g-factor increases with
increasing Mn2+ concentration for co-precipitated particles whereas
the reverse trend for sol-gel technique is observed. However, in both the
processes the saturation magnetization (Ms)
and coercivity (Hc)
increase with increasing Mn2+ concentration. In a comparative study,
the nanoparticles synthesized by sol-gel are more crystalline in
nature as compared to co-precipitated particles. |
