摘要：
The characteristics of fixation centers of cobalt domain walls are studied by two alternative methods of nuclear magnetic resonance as an echo signal under the influence of an additional magnetic video-pulse: by the effect of a magnetic video-pulse on a two-pulse echo signal and by the threshold for generating a magnetic echo signal with the combined influence of a radiofrequency pulse and a magnetic video-pulse on a sample. The degree of fixation of cobalt domain walls is shown to depend on the external constant magnetic field in a wider range as compared to lithium–zinc ferrite because of its higher magnetic rigidity.
