Аннотация: A comparative analysis of the influence of random fluctuations of the crystallographic anisotropy and surface roughnesses on the pinning of a domain wall in a nanowire has been performed in the framework of the model of a polycrystalline nanowire. The initial magnetization curve and the coercive force for these mechanisms of pinninПоказать полностьюg have been calculated. A criterion has been formulated according to which surface inhomogeneities of the nanowire play the key role in the process of pinning of a domain wall. The analytical results obtained have been verified using computer simulation.
