MAGNETORESISTANCE EFFECT OBSERVED IN Fe/Mo MULTILAYERS PREPARED BY ELECTRON BEAM EVAPORATION

Keywords： magnetoresistance

The Fe/Mo multilayers were prepared by electron beam evaporation, the microstructure and magnetic properties of the multilayers were studied by X-ray diffraction, vibratingsample 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(1.0nm)]42 multilayers,MR ratio could arrive to 0.1%. The 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.
