Effect of drying on magnetic properties of Ba1-xLaxFe12O19/polyaniline composites
Composites of Ba1-xLaxFe12O19/polyaniline were successfully prepared. By using X-ray diffractometer, the secondary phase of α-Fe2O3 was detected besides the main phase of Ba1-xLaxFe12O19. Phase percentage of α-Fe2O3 increased with the increase of La doping concentration. Lattice parameters, a and c, of the main phase were decreased with respect to the increase of the La doping concentration, x. The decrease of a and c could be attributed to the substitution of small ionic of La3+ to the larger o
