Garnet fine Particles of Bi_<1.8>Y_<1.2>Fe_5O_<12> (Bi-YIG) were prepared by coprecipitation and annealing processes. The annealing was carried out at 650ﾟC for 4h. The obtained particles were identified as garnet by X-ray diffraction. The magnetic inks were made for various Bi-YIG/binder ratios, and were coated on glass and platic substrates. The volume ratios of Bi-YIG particles were from 0.05 to 0.07 in the coated films. The size of the Bi-YIG particles was about 50 nm. The Faraday rotation spectra of the coated films shifted to longer wavelength with decreasing particle content in the films. the maximum value of the figure of merit of the coated Bi-YIG films was 2.2, whereas that value for the sputtered film having about same composition was 2.5.

采用共沉淀和退火工艺制备了Bi_<1.8>Y_<1.2>Fe_5O_<12>（Bi-YIG）石榴石细颗粒，在650℃下退火4h，经X鉴定为石榴石。磁性墨水按不同的 Bi-YIG/粘合剂比例制成，并涂覆在玻璃和塑料基材上。涂膜中Bi-YIG颗粒的体积比为0.05至0.07。随着膜中颗粒含量的减少，Bi-YIG颗粒的尺寸约为50 nm。涂膜的法拉第旋转光谱向更长的波长移动。涂覆的Bi-YIG膜的品质因数的最大值为2.2，而具有大致相同组成的溅射膜的该值为2.5。
