主 题：Condensed matter: electrical magnetic and optical Surfaces interfaces and thin films
摘 要：Based on the 4 * 4 matrix method, we present theoretical calculations of the magneto-optic polar Kerr effect with the incident energy in granular films. It is found that the simulated results are in good agreement with experimental ones. In addition, Kerr rotation and ellipticity as functions of incident angle and magnetic film thickness have been computed. The calculated results indicate that the Kerr spectra as a function of the incident angle reveal a maximum at certain incident angles and the Kerr spectra appear to be periodical and have damped oscillation as a function of the magnetic film thickness, which is important for the design of the materials in the future.
