Investigation of the Characteristics of Domain Wall Fixation Centers in Cobalt by the Nuclear Magnetic Resonance Method
https://doi.org/10.47612/0514-7506-2022-89-6-820-823
Abstract
The characteristics of fixation centers of domain walls in cobalt are studied by two alternative methods of nuclear magnetic resonance observed 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 at combined influence of a radiofrequency pulse and a magnetic video-pulse on a sample. It is shown that the degree of fixation of domain walls in cobalt linearly depends on the external constant magnetic field in a wider range, compared to lithium-zinc ferrite, due to its higher magnetic rigidity.
