Jul 17, 2012 The incorporation of La 3+, or Pb 2+, or Bi 3+ of different amounts (0, 3, 5, 10 and 15 wt%) was used to improve the densification without changing the crystal structure, since with a low doping content these ions can occupy the A site of the perovskite blocks; they can also occupy the Bi 3+ sites in Bi 2 O 3 layers.

Magnetic data from Table 3 show that ps values decrease about 10% after 300 minutes of ball milling.As discussed above, spin canting and/or CuxFe3_x04 formation can account for this reduction, meaning that site populations in &Fe204 are not appreciably affected by milling.
