P. Vaqueiro et al., SYNTHESIS OF YTTRIUM-IRON-GARNET NANOPARTICLES VIA COPRECIPITATION INMICROEMULSION, Journal of materials chemistry, 7(3), 1997, pp. 501-504
We describe a new technique using microemulsions to produce ultrafine
precursors of yttrium iron garnet. A coprecipitation of hydroxide or c
arbonate precursors was made in a W/O microemulsion medium. These prec
ursors (ca. 3 nm in size), when heated above 700 degrees C, transforme
d to YIG phase. Once prepared, YIG nanoparticles were characterized by
X-ray diffraction, transmission electron microscopy and de magnetic m
easurements.
