Oblique incidence of light propagation in magnetic anisotropic media and digital photonic device applications

To understand the propagation of optical waves in semiconductor layered media has become important in modern photonics technology, especially for transparent materials because world's industrial investment in optoelectronics is dramatically increased in the recent five years. Layered media include isotropic and anisotropic materials in which transmission and reflection of optical waves are confined by detail structural properties [1]. Thus, the optical tools related structure-sensitive magnetic properties, i.e. magneto-photonics, become useful for interface or surface analysis in the ranges of transparency of the contacting media. Magnetic anisotropy investigation is essential for the growth of magnetic thin films. Recently, hot topic in perpendicular magnetic recording is still in developing because application in high-density recording is indispensable in our future lives.
