Popis: |
Nanocrystalline Ce(1-x)Fe(x)O(2-delta) particles with different Fe concentrations (x = 0.0, 0.05, 0.10, 0.15, and 0.20) have been prepared by a gel-combustion method. X-ray diffraction data revealed the formation of an impurity free Ce(1-x)Fe(x)O(2-delta) products up to x = 0.15. This observation is further confirmed from the detailed studies conducted on 10 at.% Fe doped CeO2 using High-Resolution Transmission Electron Microscopy (HRTEM) imaging, Selected-Area Electron Diffraction (SAED) and Raman spectroscopy. DC magnetization studies as a function of field and temperature indicate that they are ferromagnetic with Curie temperature (Tc) well above room temperature. |
