Abstract

Glass of nominal composition Sr0.6La0.4Fe11.6Co0.4O19 + 12SrB(2)O(4)
was prepared by rapidly quenching an oxide melt and was then
heat-treated at temperatures from 550 to 900 degrees C to give
glass-ceramics containing fine lanthanum- and cobalt-doped strontium
hexaferrite particles and microcrystalline SrB2O4. The materials were
characterized by x-ray diffraction, scanning electron microscopy,
electron probe x-ray microanalysis, and magnetic measurements. The
coercivity of the glass-ceramic samples was shown to increase up to 427
kA/m with increasing heat-treatment temperature. The saturation
magnetization of the samples increases up to 25.0 A m(2)/kg as the
heat-treatment temperature is raised to 750 degrees C, and decreases
slightly at higher temperatures. Dissolving the nonmagnetic matrix of
the glass-ceramic prepared at 900 degrees C, we obtained submicron
powder of composition Sr0.88La0.12Fe10.74Co0.47Oy, as determined by
x-ray microanalysis.
