Effect of oxygen vacancy on ferromagnetism and electric transport of bulk polycrystalline (In0.8Mo0.05Fe0.15)2O3

We report the effect of sintering pressure on ferromagnetism and electric transport properties of bulk polycrystalline (In0.8Mo0.05Fe0.15)2O3. Structural characterization by powder x-ray diffraction, magnetic and electronic characterization by magnetometry, and ac transport measurement indicate that (In0.8Mo0.05Fe0.15)2O3 shows intrinsic ferromagnetism under suitable fabrication condition. The ferromagnetism and electronic transport property of (In0.8Mo0.05Fe0.15)2O3 can be tuned by the oxygen vacancy in the sample.
