英文摘要The detailed micro structures of Ni80Fe20/Fe50Mn50 superlattices have been characterized using both x-ray diffraction techniques and transmission electron microscopy. The obvious layered structure, typical column structure and twins which exist in Ni80Fe20/Fe50Mn50 superlattices were observed through performing transmission microscopy. By combining the technique of low-angle x-ray reflectivity (specular and off-specular scans) with the anomalous scattering effect and high-angle x-ray diffraction (using conventional x-ray), we quantitatively analysed the microstructural variation as a function of annealing temperature. It is found that the lateral correlation length, the (111) peak intensity of the superlattices and the average multilayer coherence length all increase with a rise in annealing temperature. The correlated roughness slightly decreases after annealing, while moderate annealing can decrease the root-mean-square roughness at the interfaces of Ni80Fe20/Fe50Mn50 superlattices. The obtained microstructural knowledge will be helpful in understanding the magnetic properties of the Ni80Fe20/Fe50Mn50 exchange bias system.
