Abstract

We developed a new magnetooptical Bi_1.8Y_1.2Fe₅O₁₂ nanoparticle hybridized material which was composed of Bi_1.8Y_1.2Fe₅O₁₂ nanoparticles and a methylmethacrylate matrix, with and without polymethylmethacrylate. The Bi_1.8Y_1.2Fe₅O₁₂ nanoparticles were prepared using coprecipitation and annealing processes. The hybridized system was prepared by mechanical milling. In this system, polymethylmethacrylate was a very important functional material as a dispersant. Without polymethylmethacrylate, the Bi_1.8Y_1.2Fe₅O₁₂ nanoparticles aggregated. The magnetooptical properties of the solidified clear materials were measured.
