ANGLE-DEPENDENT TRANSMISSION FOR VISIBLE LIGHT OF MAGNETIC GRANULAR THIN FILMS

Giap Van Cuong

Abstract


      The transmission for visible light (T), with wavelengths from 560 to 695 nm, was investigated at various light incident angles of 0 ¸ 45 degree for the surface normal of samples (φ) as a function of Co contents for magnetic granular films Cox-(Al2O3)1-x, where x = 0.10 ¸ 0.45. This investigation was carried out under an external magnetic field fixed at 4 kOe to ensure for all the Co-granule magnetization being kept in a fixed incident light propagating direction. Results showed a rather remarkable angular dependence of T(φ) on the Co content for different wavelengths. It was attributed the behavior of this to be dependent on the so-called magnon-photon interaction.
