The Fe/Mo multilayers were prepared by electron beam evaporation,the microstructure and magnetic properties of the multilayers were studied by X-ray diffraction,vibrating-sample magnetometer(VSM) et al.The experimental results revealed that the Fe/Mo multilayers in our experimental conditions behaved magnetoresistance effect with a sharp peak on magnetoresistance(MR)ratio curve,and magnetoresistance is easily saturated at low applied magnetic fields.For[Fe(1.5nm)/Mo(10.nm)]42 multilayers,MR ratio could arrive to 0.1The antiferromagnetic interlayer coupling could be observed in some films at room temperature.The strength of the antiferromagnetic interlayer coupling J in the films is low because of the low saturation field Hs.The relationship between magnetic properties and microstructure was also discussed in this paper.

The Cu25Nb75 and Ni45Nb55 amorphous films with about 50Onm thickness were pre-pared by ion beam assisted deposition (IBAD). Potentiodynamic polarization measure-ment was adopted to investigate the corrosion resistance of samples and the tests were carried out respectively in 1mol/L H2SO4 and NaOH aquatic solution. The corrosion performance of the amorphous films was compared with that of multilayered and pure Nb films. Experimental results indicated that the corrosion resistance of amorphous films was better than that of the corresponding multilayers and pure Nb films for both Ni-Nb system with negative heat of formation and Cu-Nb system with positive heat of formation.
