I examined on the magneto- optical effect by media of a TM/NM multiple layered film, and has been carried out Kerr angle, ellipticity, reflectivity by graphs through the computer simulation and compared them to their experimental value.
As I compared each layer’s materials and their thickness, find out the bigger magneto-optical effect than having another condition. I am also able to find out some materials giving better reliance of S/N ratio in determinig the refractive index and thickness. It is regretted that could not calculate more close value than the experimental value that may be able to obtain. If should be simulated accurate value of optical constant each wavelength. The results of simulation are as follows. 1. In case of single layer film of Co or Fe, there are big difference between experimental and theoritical value in the range of short wevelength. 2. In case of Co/Pd,the reliance of composition, the variable tendency of magneto-optical kerr rotaition angle for Co thickness is fully corespond to experimental and theoritical value. 3. In case of Fe/Cu and Fe/Ag, magneto-optical Kerreffect in the near Cu and Ag absorption band correspond to experimental and theoritical values than the Fe single layer that has tendency of increasing. 4. In case of TM/NM multilayer, Magneto-effect by refraction of multilayer connecet with the absorption band of NM closely.
