To study the effect of microstracturcs,long-time
grinding and nonmagnetic phase on magnl;tic properties of
barium fe rrite, isotropic samples of ba rium ferrile magnets,
BaU.6Fc203. were prepared by ce ra mics and co -
precipitation methods. Magnetic measurments indi ca tes a
higher demagnetization of the samples prepared by <.:hemical
method due to lack of rcmcnant stress and crystallographic
imperfect ions in th is case. Also, the inter med iate
nonmagnetic phases is less in samples prepared hy chemical
method. The optimum si ntering temperature for maximum
store of magnet ic e nergy is 925-950°C fo r che mica l and
950- 1000°C for ceramic methods.
