Preparation of Mn doped CeO2 nanoparticles with enhanced ferromagnetism
Spherical-like CeO2 and Mn-doped CeO2 using 6-aminohexanoic acid as surfactant exhibit enhanced ferromagnetism. The optical absorption spectra reveal a red shift with a band gap of 2.51 eV. The mechanics of ferromagnetism and the red shift were analyzed. These results provide a promising platform for developing a dilute magnetic semiconductor in spintronics. (C) 2017 Elsevier B.V.
