Abstract :
This paper presents the study using X-ray photoemission electron microscopy (XPEEM) of a simple and well defined single-layer necked Permalloy nanowire, which provides an artificial pinning site for domain wall. The XPEEM images provide direct evidence of the formation of the head-to-head or tail-to-tail domain wall by controlling the magnetization process.
