In the present investigation, the samples with chemical composition BaAl2Fe12O22
have been synthesized using perfect stoichiometric proportions of nitrates by
chemical co-precipitation technique. The pellets of 15 mm diameter were
prepared and sintered at 1100? for 6 and 4 hrs and at 1000? for 6 hrs separately.
The characteristic studies have been done using XRD, SEM, electrical and
magnetic properties. XRD studies of the samples showed hexagonal Y-type
structure with unit cell dimensions 'a' and 'c' varies from a = 5� to 6� and c = 43�
to 47� pertaining to space group P63/mmc (No. 194). The variation in the values of
lattice parameter has to be recorded with increase in Mn-Zn conc. The magnetic
properties of prepared Y-type Ca-hexaferrite powder were investigated by VSM
studies at 15,000 Gauss magnetic field. The transition temperature and activation
energies have been investigated from electrical behavior of the samples.
