Magneto-Optical Properties of Bi-YIG Particles Dispersed in a Plastic Binder

Abstract

Abstt-Gamet fine particles ofBi18Y12Fc5012(Bi-YIG)were prcparcd by coprecipitation and annealing ploccsscsThe annealing was caicd out at650C for4hThc obtained particles wcre idcntified as gamct by X-my difffactionThe magnetic inks were madc for various Bi-YIGbind-eHatiosand werc coated on glass and plastic substratesThc volume I atios of Bi-YIG particlcs wclc flom O05to O70in thc coatcd filmsTho sizc of the Bi-YIG particlcs was about50nm
