Abstract

The structural analysis of strontium hexaferrites SrFe x O19 (for x = 12, 11 and 10) and substituted samples Sr0.7Nd0.3Fe12 − y Co0.3O19 (for y = 0.3,1.3 and 2.3) prepared through the citrate precursor method is shown. Nd and Co substitution modifies saturation magnetization (M S ) and increases coercivity (H c ) in samples heat-treated at 1100°C for two hours. Mössbauer analyses show different iron occupancy and the influence of the Fe3 +  content is particularly emphasized. Hematite segregation is observed for some compositions. Samples with low Fe3 +  content show the best magnetic properties with no secondary phase segregation.
