Abstract

The effect of Ce ions substitution at Fe ions site on the microstructure, humidity sensing and magnetic properties of magnesium ferrite was investigated. MgCexFe2-xO4 ceramics with x = 0.00, 0.02 and 0.04 were prepared using sol-gel auto combustion technique. X-ray diffraction analysis confirms the formation of cubic spinel structure of magnesium ferrite for all samples. However a second phase of CeO was also present in samples with Ce substitution. Scanning electron images show porous structures with irregularly shaped grain. Sample with composition x = 0.04 has the highest percentage of porosity and smallest grain size. This sample also has the highest sensitivity towards humidity. Magnetic hysteresis loops show a soft magnetic material behavior with low coercive force for all samples. The magnetization decreases while the coercive field increases with Ce substitution.
