Aerosol Incident Angle Dependence of Optical and Magnetic Properties of Bi:YIG Films Deposited with Aerosol Deposition Method  

Shin, Kwang-Ho (Department of Multimedia Communication, Kyungsung University)
Abstract
Bismuth-substituted yttrium iron garnet($Bi_{0.5}Y_{2.5}Fe_5O_{12}$) films were deposited with the aerosol deposition method and their magnetic and optical properties were investigated as a function of the aerosol incident angle. The optical transmittance of Bi:YIG increased about 80% with increasing the aerosol incident angle from 0 degree to 30 degree, due to decrease of the defects which were formed from agglutinations of the Bi:YIG particles inside and/or surface of the film. The coercive force also decreased largely with increasing the aerosol incident angle due to the reduction of the collision energy between the particles and the substrate and the decrease of the defects.
