Nanocomposite of CeO₂ and High-Coercivity Magnetic Carrier with Large Specific Surface Area

Figure 1

(a) The measured PXRD patterns of the matrix-free samples (Cu-K_α radiation used) with the corresponding refined patterns (full black lines). (b) The measured PXRD patterns of the CoFe₂O₄/CeO₂ nanocomposite samples (Co-K_α radiation used). White circles and black triangles indicate the Bragg positions corresponding to the CoFe₂O₄ (PDF database, card number 00-022-1086) and CeO₂ (PDF database, card number 01-081-0792), respectively. (c) The examples of the high-temperature PXRD patterns of the v04 sample. Stars correspond to the reflections from the platinum heating strip. The dependence of the on the with the corresponding error bars is depicted in the inset.
