| Abstract: | Magnetic materials FeMnO_3 and FeMnO_(3 )doped with Mg or Ag were prepared by citric acid gel method using Fe(NO_3)_3 and Mn(NO_3)_2 as raw materials.The products were characterized by XRD, TEM, TG-DTA etc..The results of experiment showed that the crystal size of FeMnO_3 and FeMnO_3 doped with Mg or Ag was less than 30 nm, and this method could reduce preparation procedure. It was beneficial to doping and preparing. Mechanism of preparation was also discussed. |
