摘要：

We have grown epitaxial Co/Cu multilayer samples at different temperatures using MBE on sapphire (<11(2)over bar 0>) substrates with a 30 Angstrom layer of Nb as a buffer, and find a remarkable correlation between the sharpness of X-ray rocking curves and the magnitude of the GMR. Whereas the peak GMR for our previous samples grown on GaAs was never greater than 26%, the maximum GMR of samples grown on sapphire under optimal growth conditions was as high as 50%.
