Paper Abstract

This paper gives optical and magneto-optical (MO) characterization results (index of refraction, absorption coefficient, thickness, Faraday rotation, and coercivity) obtained from bismuth-doped dysprosium iron garnet samples. These samples were prepared under differing sol-gel processing conditions and were characterized using the Ultimate Ellipsometer. After first describing the design and measurement capabilities of the Ultimate Ellipsometer (Simpson, 1995), we then describe how various processing parameters, such as spin speed and annealing temperatures, affect the bismuth iron garnet material's optical and MO properties.
