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.

Bi_ <1.8> y_ <1.2> Fe_5o_ <12>（Bi-yig）的石榴石细颗粒是通过重新沉淀和退火过程制备的。退火在650°C进行4H进行。通过X射线衍射将获得的颗粒鉴定为石榴石。将磁性油墨用于各种Bi-YIG/粘合剂比率，并涂在玻璃和platic底物上。在涂层膜中，Bi-YIG颗粒的体积比为0.05至0.07。 Bi-YIG颗粒的大小约为50 nm。涂层膜的法拉第旋转光谱转移到更长的波长，而膜中的颗粒含量降低。涂层二线膜优点的最大值为2.2，而具有相同成分的溅射膜的值为2.5。
