Resumen o descripción
An analysis of the properties of a family based
on lead-barium substitution in the M-type hexaferrite is presented.
The samples were prepared by the ceramic method
according to the general formula PbxBa1−xFe12O19. The
barium content was varied with x = 0.1, 0.3, 0.5, 0.7, and
0.9; no secondary phases were detected in any composition.
Rietveld refinement analysis was done in order to determinate
crystallographic parameters, content of phases and
degree of substitution. The effects of the barium on the
morphological and magnetic properties were studied. Iron
Mössbauer spectroscopy was used for determining the hyperfine
parameters of the iron nucleus and their environment;
also, the cationic occupancy was evaluated and the
results were checked with X-ray refinement results.
