Enhancement of the phase transformation temperature of γ-Fe2O3 by Zn2+ doping
Abstract
The phase transformation temperature of γ-Fe2O3 to α-Fe2O3 is increased with Zn2+ doping and enhancement of the transition temperature by ∼100 °C is obtained for doping of ≥15 mol% Zn in nanocrystalline γ-Fe2O3 synthesized by an autocombustion method.
