A testing system for the light intensity modulated direct overwrite magneto optical multilayered films is designed successfully.

Monte Carlo simulation of spin reorientation in magnetic multilayers;

A kind of magnetic multilayers microwave absorbent is prepared with magnetron sputtering.

On-line study of GMR in Au /Fe magnetic multi-layers during the ion beam mixing;

Then the transformation of samples from magnetic multi-layers to magnetic granular films and the anisotropic growth of magnetic granule were discussed, and proved the anisotropic growth by TEM experiments.

Based on the local energy minimum via coherent rotation of the magnetic and classical thermal activation, magnetization processes of magnetic multilayered films with both the bilinear and biquadratic exchange couplings are investigated.
