Preparation, magnetic characterization, and optical band gap of EuTiO3 nanoparticles
Perovskite-type polycrystalline EuTiO3 (ETO) nanoparticles were synthesized using the simple sol-gel technique. We investigated the magnetic properties of the as-prepared ETO nanoparticles and revealed the G-AFM phase below the Neel temperature (T-N). Furthermore, the transition from the G-AFM order to the FM order, induced by magnetic field, was also demonstrated. The optical band gap of 1.03 eV for the as-prepared ETO nanoparticles was determined from the UV-visible absorption spectra. (C) 2010 Elsevier B. V. All rights reserved.
