|Title:||Nanocrystals Of Bafe12o19 Obtained By The Proteic Sol-gel Process|
|Abstract:||Nanocrystals of BaFe12O19, with a small amount of the BaFe2O4, were obtained by means of the proteic sol-gel process together. The results demonstrated that the magnetic and crystallographic properties are dependent on the calcination temperature and the values of Mr/Ms are very close to 0.5, which is the expected value by the Stoner-Wohlfarth model. The best calcination temperature was at 900 °C with Ms=55.5 emu/g, Hc=4.1 kOe and crystallite size 39 nm. © 2006 Elsevier B.V. All rights reserved.|
