Optical and magnetooptical properties of BioYj 2Fe4GaiOi2 nanoparticles

摘要

We synthesized a new magneto-optical nanoparticle material Bii 8Yi 2Fe4Gai0i2 (BYIGG) with substitution of gallium by iron. It was prepared using coprecipitation and annealing processes. High Energy ball-milling was used to mill the nanoparticle to tens of nanometer range, The thin-film coated shows improvement of transmittance because of the substitution. A simple model for scattering and Faraday Effect was used to calculate the transmittance and Faraday Rotation angle, which shows have a good match with the known experimental result.
