摘要：

Enhancement of MR ratio with addition of Cu/Ag capping layers was found in NiFe/Cu/Co GMR films prepared on MgO substrates with Pt/Cu buffer layers. Simulation of the MR ratio was carried out using the theoretical model given by J. Barnas, A. Fuss, R.E. Camley, P. Grunberg; W. Zinn [Phys. Rev. B 42 (1990) 8110] to clarify the origin of the enhancement of GMR. The results show that the specular scattering plays an important role in the films and the enhanced GMR can be explained by assuming the increase of specularity factor of the capping layer.
