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
