Abstract

The effect of the structure of interfaces on the magnetoresistance properties of Co90Fe10/Cu su-perlattices has been studied by the method of nuclear magnetic resonance (NMR). It was found that, with increasing annealing temperature, the fraction of highly perfect interfaces decreases. It is demonstrated that the deteriorated state of interlayer boundaries results in a decrease in GMR.
