Abstract
In this letter, we report on a nanodomain wall thin-film structure and its fabrication. The core unit of this structure consists of a magnetic nanodot layer sandwiched between a magnetically free layer and a pinned layer. When the magnetizations of the free layer and the pinned layer are unparallel, a nanodomain wall is formed in the magnetic nanodot. Based on this concept, a nanodomain wall film structure with a Ni/Al2O3 nanodot layer is prepared. Since the free and pinned layers are coupled through magnetic nanodots, a displacement of free layer M–H loop from zero field is observed. By measuring the displacement field of the free layer, the nanodomain wall energy is estimated.
