A Study of the Micromagnetic Structure of Domain Walls in Ultrathin Magnetic Films

摘要

A numerical method is used to study the structure and energy of the Neel domain wall in an ultra-thin magnetic film of the permalloy type. It is shown that the structure of the Neel domain wall is determined by a pattern of changes in the magnetostatic energy, which is divided, so as to decrease its value, into the following three regions: the core region and two regions of lateral turnarounds.
