Domain walls with alternating magnetic order in a model with dipolar coupling
This work analyzes domain walls connecting two y-alternating uniform magnetic states in a 1D chain of magnetic islands. The analysis reveals that these domain walls have a site-by-site alternating order and possess a large longitudinal magnetic moment. A continuum theory is developed to describe their structure, showing that the transverse magnetic moment depends on whether the chain length is odd or even, highlighting topological effects.
