Abstract: The magnesium manganese – Zinc ferrites having chemical formula MgMnxZnxFe2-2xO4 for x varying from 0.0 to 0.6 in the steps of 0.1 have been synthesized by standard ceramic technique. The variation of Mn – Zn substitution has significant effect on the structural and magnetic properties of magnesium ferrite. The phase identification of the powders performed using X-ray diffraction technique shows presense of high purity cubic phase and absence of any secondary phases. The lattice constant increases from 8.35 to 8.43Å with increase in Mn-Zn substitution x. The Pulse field hysteresis loop tracer technique is used to study the magnetic properties of the prepared samples. The Saturation magnetization (Ms ), remanance magnetization (Mr ), Coercivity (Hc ) and magneton number (nB) are measured at room temperature. The Saturation magnetization (Ms ) and magneton number (nB) increases upto x = 0.3 and then decreases with increase in Mn-Zn substitution x in magnesium ferrite.AC Susceptibility measurement confirms the decrease in Curie temperature with increase in Mn-Zn substitution x.
