Chemical Synthesis of Cobalt Nanowires in an External Magnetic Field and their Characterization by NMR
Abstract
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 shown. This method can be used for NMR estimation of the pinning force of domain walls and the coercive force of cobalt nanowires in order to optimize their chemical synthesis in an external magnetic field for potential use in rare-earth-free permanent magnets, sensors, and other applications.
