| Abstract: | Mixed ferrites belonging to the type Mn0.9Zn0.1Fe2O4
have been prepared by the double sintering method and by the
chemical co-precipitation for comparing their magnetic properties. Sintered and
precipitated ferrites exhibit different characteristics, especially in their
magnetic properties like magnetization (Ms),
coercive field (Hc) and
Curie temperature (Tc).
The sintered particles were size reduced in order to compare with the nanosized
co-precipitated particles. The effect of grinding has also been studied.
Particles have been collected at regular intervals of grinding and their
properties have been studied. The increase in the coercive field has been
recorded by a hysteresis curve tracer confirming size reduction. X-ray
diffraction studies confirmed the structure and consequent size reduction. |
