Abstract

Magnesium ferrite of composition Mg0.993Fe2.007O4 was quenched from 1000°, 1150°, and 1295°C. The rate of inversion at 450°C was followed by Curie temperature measurements in a thermo-gravimetric analyzer. The inversion process possessed the features of a nucleation and growth transformation. It is postulated that short range order within the octahedral sub-lattice plays an important role in cation ordering in Mg ferrite.
