摘要：
The effect of annealing on the oscillatory behavior of giant magnetoresistance (GMR) is studied in Co/Cu multilayers. Annealing at 200 degrees C in vacuum reduces the height of the Ist peak of GMR oscillation significantly. However, the degradation of interface measured by X-ray diffraction is not large compared with the change in GMR. Microscopic change of the interface state causes ferromagnetic interlayer coupling between adjacent Co layers and diminishes the Ist GMR peak. The 2nd GMR peak, on the other hand, is not so sensitive to the degradation of the interface.
