Abstract
We present a new approach to calculating magnetic fringing fields from
head-to-head type domain walls in planar magnetic nanowires. In contrast to
calculations based on micromagnetically simulated structures the descriptions
of the fields are for the most part analytic and thus significantly less time
and resource intensive. The models presented begin with an intuitive picture of
domain walls, which is built upon in a phenomenological manner. Comparisons
with fields calculated using micromagnetic methods show good quantitative
agreement.
