摘要
The effects of annealing on the structure, magnetic hysteresis, and magnetoresistance of [Co90Fe10(15 )/Cu(23 )] (n) superlattices with Cr and Co90Fe10 buffer layers of different thicknesses have been studied. The optimum temperature and time of annealing that increase the magnetoresistance were shown to depend on the buffer layer thickness. The coefficients of effective interlayer diffusion due to the annealing have been determined.
