Investigation of Effect of Mn doping in Magnetic Properties of ZnFe2O4.

In present study, the effect of Mn doping was investigated in Zinc ferrite (ZnFe2O4) nanopartclicles (ZFNPs). The annealing effect on the structure and magnetic properties of ZFNPs were investigated at different temperatures. These particles were synthesized by using Chemical co-precipitation method (CBD). The ZFNPs were characterized by using by XRD, Transmission Electron Microscopy (TEM) and Vibrating sample magnetometer (VSM) for determination of their structural as well as magnetic properties. The effect of annealing temperature on the lattice constant of ZFNPs were clearly observed and the results of TEM and XRD were in good agreement with the average particles sizes. VSM results show the behavior of ZFNPs were changes from super paramagnetic to ferromagnetic as annealing temperature increases. [ABSTRACT FROM AUTHOR]
