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.
