摘要

The possibility of measuring the degree of fixing (pinning force) of domain walls in cobalt nanowires by the NMR spin-echo method under the action of an additional magnetic video-pulse on a two-pulse echo is demonstrated. This method can be used for NMR estimation of the pinning force of domain walls and the coercive force of cobalt nanowires to optimize their chemical synthesis in an external magnetic field for potential use in rare-earth-free permanent magnets, sensors, and other applications.
