Interlayer exchange coupling was first observed in Fe/Cr/Fe(001) sandwiches and Gd/Y multilayer films. In Gd/Y, the interlayer exchange is an oscillatory function of the Y thickness. Now strong interlayer exchange effects have been found in many multilayered structures based on ferromagnetic transition metals such as Fe/Cu, Ag/Ni and Fe/Au multilayer films. The multilayer films based on Fe-N alloy attracted

Due to the applications in electronics and optics in the past two decades, ferroelectricthin films (BaTiO3, PbTiO3, (Pb1-xLax)(ZryTi1-y)O3（PLZT x/y/1-y）, LiNbO3, Bi4Ti3O12,etc.)have been widely investigated. Especially, ferroelectric thin film memory, combining the ad-vantage of semiconductor memory with that of magnetic memory, has properties including highspeed, high density, nonvolatility and good radiation hardness, and can be compatible

Optical constants, n-refractive index and k-extinction coefficient have been determinedfor Al-N-F and Al-O-F dielectric thin films, with n approximate to 1.4 and k about 0.01,prepared in d. c. magnetron sputtering.system. A new solar selective absorbing surface ofgraded Al-N on Al base layer with Al-N-F antireflection film has been fabricated, and agood agreement is obtained between computed and experimentally measured reflectances andabsorptances for the selective absorbing surface which has a solar absorptance around 0.97(as-deposited) and 0. 95 (heat-treated at 450℃ for 1 h in vacuum). The solar selective absorb-ing surface has also been analyzed by Auger and ESCA.
