abstract = "Micromagnetic modeling is used to study the energetics of magnetic
switching of single-layer permalloy nanowire. The energy landscape
of the system is studied using Nudged Elastic Band method. Using
different initial guess trajectories for NEB minimization several
alternative minimal energy transition paths were found
corresponding to possible scenarios of magnetic switching of the
nanowire through nucleation and propagation of transverse domain
walls. Dependence of energy barrier for DW nucleation on lateral
sizes of the nanowire has been studied. Besides that, the effect
of additional constant external bias magnetic fields (longitudinal
and transverse) on nanowire switching has been explored. It has
been shown that presence of rectangular shape notch on the
nanowire long side leads to the appearance of local minimum on the
energy profile. Thus artificially created notches can be used for
DW pinning.",
