The indirect transition process of Neel domain wall polarity during magnetization reversal in magnetic thin film element

摘要

There are two patterns of the transition process of Neel domain wall in magnetic thin film elements. One is the direct transition from positive polarity (N_+) to negative one (N_). And the other pattern of N_+ ->Nct ->N_ is indirect transition process recurring to cross-tie wall (Nct). The latter pattern is observed and analyzed in this paper.
