Abstract :
We developed a new magnetooptical Bi1.8Y1.2Fe5O12 nanoparticle hybridized material which was composed of Bi1.8Y1.2Fe5O12 nanoparticles and a methylmethacrylate matrix, with and without polymethylmethacrylate. The Bi1.8Y1.2Fe5O12 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 Bi1.8Y1.2Fe5O12 nanoparticles aggregated. The magnetooptical properties of the solidified clear materials were measured.
